Feature: Roanoke Wildwood Volunteer Fire Department
Roanoke Wildwood Volunteer Fire Department, located in Littleton, NC, is one of the most modern fire departments in the Lake Gaston, North Carolina area, providing services for over 10,000 full-time residents covering approximately 23 square miles in Northampton and Warren Counties. They describe themselves as “a group of men and women who share the love for what we do.” The department’s Chief Lorenzo Wilkins was named the 2019 Person of the Year by the Lake Gaston Community Center for his exemplary service in the community. This community focus characterizes the entire department, who say that they’re a family “and our community are family as well.”
Their pumper, built on a Rosenbauer Warrior Chassis, was originally a demo unit built by C.W. Williams. Joel Callihan says that C.W. Williams learned all about the FireTech options in building this truck, wanting to get the most out of FireTech’s “unmatched performance.”
This truck features a narrow 96” cab for negotiating tight areas. The front is lit up by a set of FireTech headlights, featuring the signature halo park lamps, as well as the FireTech 72” Brow Light, producing 28,512 raw lumens through Spot, Flood, and Scene optics. The truck is a high side pumper, which means the hard suction and other accessories commonly stored on the sides of the truck are instead stored inside upper compartments, and the body sheets extend all the way up the back of the truck. This makes it a perfect application for the FireTech Guardians mounted around the sides. The Guardian’s asymmetric optic shines light down and out, and, when mounted at the outermost edge on the high side sheets, produces maximum light around the vehicle. The Guardians are also thick enough to shine light straight to the ground, illuminating past the oversized hardware of the Amdor roll-up doors and shining light as close as possible to the sides of the truck.
The compartments are lit up by FireTech Heavy Duty strip light fixtures, and FireTech Sub-Aqua Undercarriage Lights illuminate the ground around the exterior. The rear of this truck is particularly difficult to light, but C.W. Williams tackled this problem by using three WL-3500 work lights on station mounts on the left and right, in addition to a centrally-mounted Guardian. The combination of symmetrical optics in the work lights and asymmetrical optics in the Guardian give a much broader light coverage at the back of the truck than a single system could produce alone.
Aside from the awesome (we think!) scene lighting package, the Rosenbauer Warrior features three windshield wiper blades, providing a safe, clear view of the road in inclement weather. The rear step is lowered to allow for an ergonomic step up for pulling hoses off the rear. Lastly, Rosenbauer designed this truck to have storage in the step-wells for eight spare air cylinders and two fire extinguishers.

Scene Lighting Tips: Lighting the Front Corners
The corners off the front of an apparatus cab can make it difficult to eliminate dark areas with scene lighting. Southeast Volunteer Fire Department in Texas found a unique way to handle this problem, using a 72″ FireTech Brow Light paired with two outward-angled MiniBrow Lights on each corner of the cab.
The 3-LED MiniBrow Lights, which use flood optics, throw light in both 45 degree directions. This setup is useful for off-angle positioning on scene and address spotting.

All three light fixtures are mounted on a custom mounting bracket. The front of the cab can often produce a shadow on the ground in front of the rig. This bracket places the lights forward of the leading edge, ensuring no light is blocked by front edge of the cab.

Every fire department’s got one of them, or if they don’t, they know one of them: the person who knows every little model number and fact about every light fixture on the market. They can state how many flashes per second, how many lumens, and what the year a specific fixture was released. But, as valuable as all that data is, can this person also articulate where the optimal placement of each fixture is so that firefighters aren’t blinded when they are on scene at their next emergency?
HiViz LEDs manufacture technologies designed to help firefighters work more effectively after dark. Often, firefighters and lighting manufacturers alike get side tracked with things like making sure they consider the number of LEDS, and the number of lumens. In addition, they must keep in mind, the placement of other firefighting appliances on their apparatus so that existing scene lights do not get obstructed. With all of these things to keep in mind, the fundamentals of a complete and rock-solid scene lighting package can get overlooked.
By keeping the following four fundamental principles in mind, your apparatus specifying committee can build a truck that not only looks sweet, but also gives you an edge when you are out at night saving lives and protecting property.
The name of the game in working after dark is uniformity. The intensity is less important; the number of times the firefighter’s eyes have to transition from very bright light to very dim light is what causes strain on the operator. It is more important to have an even intensity of lighting around the vehicle and fire scene than it is to have one spot in particular extremely well lit. Consider installing a greater number of fixtures with a lower intensity each, around the apparatus to create an evenly illuminated work space. HiViz LEDs can even draw your apparatus digitally before manufacturing to help you visualize how the beam patterns will perform.

Humans have evolved to work with the sun shining down from overhead. As such, leveraging the evolutionary science and biology of our species during spec writing is helpful in reducing glare on fire scenes.
Here’s the science: humans have two eyeballs each recessed in to a socket on the frontal bone of the scull. Above that socket, there is a bony structure called the supraorbital ridge over which the eyebrows typically align. When the sun shines down on a human’s skull, this bony structure, coupled with the eyebrows and eyelashes, casts a shadow which typically occludes the eye and prevents the sun from shining directly in the eyes of people as they work. When specifying a fire apparatus, firefighters should keep the basic biology of the human body in mind, and specify scene lights which can be placed as high overhead as practical, so that the Firefighter’s PPE and the natural shape of the human skull help prevent glare from hitting the crews in the eyes at night.
Lights can be placed high up on the body, on poles, or even on light towers to help reduce glare.
Light mounted overhead casts a shadow over the eye of the firefighter. Wearing PPE can help reduce the height needed to prevent glare, but the principles of illumination remain the same.
Light doesn’t bend! Think about fixture placement and the shadows that will be created when you select a mounting location! If you mount a scene light with asymmetric optics on the side of a stepped pumper body (say, on the vertical surface near where the hard suction may be attached), if the beam shines “down” and “out” from the fixture and a horizontal portion of the body is below it, a shadow will be cast along the edge of the body on the ground. In these situations, consider bringing the fixture out towards the edge of the apparatus to prevent these shadows from occurring. Light can not bend around the profile of the truck, if its obstructed, you will have a shadow.
Moving the fixture towards the edge of the apparatus body helps prevent shadowing
You’ve only got so much hose! The vast majority of the time, when operating off the fire apparatus at night, you will be tethered to the apparatus by a piece of hose. When writing a specification for scene lighting on a fire apparatus, consider the length of hose and the most frequent operating characteristics of the apparatus for scene lighting design. If the truck has 250’ of cross lay, there is no need for scene lights than can shine 1,000 feet down the road. Focus on the areas you can reasonably expect to work in and supplement your scene lighting package with portable or battery/generator/extension cord powered fixtures for the “what if” situations.
Know how much hose your apparatus will have- this is the practical work area to illuminate.

Hey what’s up. It’s Sam from HiViz LED Lighting FireTech Lights.
So today, I’m going to do a little demo on compartment lights and we get asked all the time, “What makes a FireTech compartment light different or worth the money when comparing to the other types of compartment lights in the industry?”
Setting FireTech Apart from the Competition
This is one of ours, we’ve taken it apart, so you can see the inside of it. I’ve actually got the end cap off.
The 2 BIG Differences – Durability and Thermal Management
One, this thing is all aluminum, so the fixture itself is more durable than most compartment lights, but it gets into a lot deeper where we can dissipate heat a lot better, so the aluminum is great for of course the structure rigidity, but of course the thermal management as well.
3 Basic Styles in Compartment Lights Around the Industry
Let me just show you a couple of styles. There are basically three styles.
Style Number 1 – the Cheap, Low Cost Option
If you look at “Style 1,” this is kind of your cheaper LED compartment light.
It’s going to be a round poly tube that just goes on the inside and it’s clipped inside of the body. That poly tube has a circuit board, and that circuit board has LEDs on it and its usually a fiberglass circuit board. That circuit board runs the length of the compartment.
If you look at it from a side view, and this is the side view and it’s got — we put the circuit board this way, going inside and it’s clipped on to the body with a few plastic clips. The wiring comes in the top side. The circuit board clips together at the inside of those pins. So you can push it inside. When those pins get pushed together, the boards lock in place and it’s inside that poly tube.
That’s a low cost way to do it and it’s fine because these things are fairly bright. But the problem with this is that LED themselves dissipate heat off the back at the chip, so if the light is dissipating heat off the back at the chip and they are just on a fiberglass circuit board, then there is nowhere for that heat to go and then because that circuit board is inside of a plastic tube, it vibrates back and forth as a truck goes down the road.
The fiberglass itself is prone to failure and then the junction where that pins interact is prone to failure and then of course the whole thing being plastic just takes one good whack from a K12 and that thing is trash.
Style Number 2 – Better Housing and Waterproofing, But Low Grade
The other, “Style 2” is a little bit better and this is the style where you’re having an aluminum extrusion, but the circuit board is cut and built in a whole long batch and then it’s cut in sections and put inside the housing.
What happens is these circuit boards are totally encapsulated in an epoxy batch.
Epoxy encapsulation keeps them from getting problems with water. It keeps them waterproof, but the problem with that is that the epoxy ends up an insulator and then of course you have a temperature problem, so let me just draw this out.
When you look at this type of extrusion, we’ve got a little pocket, and then we’ve got the rest of that pocket and this might go up.
So this type of extrusion, the circuit broad that sits in here slides in. The board sits in the middle of this epoxy encapsulation and it’s got LEDs on the top.
What happens here is the whole piece is sort of similar towards were it’s extruded, but the circuit board can’t get rid of the heat because this whole area around totally encapsulating around where the chips are is that epoxy, and epoxy is like a plastic and just like with anything, plastic is an insulator.
So this style is a lot better than “Style 1” because this is more durable. It’s more waterproof. It gives you a little more light up because it does have some strength to it.
Style Number 3 – The FireTech Brand Approach
But “Style 3” is the FireTech style.
We take the circuit board and we built this thing more like we do with one of our scene lights, the FireTech Brow Light.
The way our fixture goes, this is the housing right here.
If you look at it down the side, it’s shaped like a U. Sitting directly on the housing, is our circuit board. So on top of the circuit board, of course sits the LEDs. But the heat from these LEDs pushes back into the housing and this aluminum housing has ribs on it and those ribs act like a heat sink.
This whole big aluminum housing, because the circuit board is banded to the aluminum housing allows way better thermal dissipation and the key to the success of an LED over the life of an apparatus is the ability to manage the thermal load, the ability to shed heat.
The Problem with Standard LED Compartment Lights
Because typically, if LEDs get too hot, they break down and they just fail.
So the problem is when you band these together, now you’ve got big void space, you know water getting inside.
The FireTech Compartment Light Solution
What we do is we epoxy and encapsulate once the fixture has been manufactured, up to the top half of the LEDs, so the board is banded to the housing and then we epoxy the top half and keep the open face, the phosphorus face of the LED out to the atmosphere.
But if you look here, you will see how that whole area will be covered in the epoxy potting, so that keeps it totally waterproof.
But then we also add a little ridge on the top side and have a gasket right here. If you look at this piece, actually that gasket of material goes on the topside and then we add a lens. That lens goes on top of the gasket when you pop it in place, it creates a waterproof seal.
We not only have a waterproof design where the circuit board is in an epoxy encapsulate, you also don’t get water on the LEDs. It also has a lens on top of it, it is waterproof, so the whole housing is designed to be used in higher vibration environments because you don’t have to worry about the “Style 1” type fixture problems, where the circuit broad rattles around inside of the piece of plastic tubing. It is designed for high temperature environments, so like a closed compartment or like a compartment even the underside of a fire truck, where we’ve got dirt, junk and trash, all over these things we’re able to dissipate heat because of these vents and the aluminum housing.
We’ve also got the durability of having all aluminum mounting points.
When you look at these, the lens gets installed on the top side and then we have an aluminum end cap. This light here has actually been on my truck for a couple of years and we just pulled it back for some testing, but this all aluminum end cap bolts into this extrude housing and when it’s bolted on, there is a little rubber gasket that goes over here.
It allows for mechanical fastening of the housing all the way to the fire truck body, so the likelihood of this thing getting knocked off the truck is very low because of this aluminum end cap and aluminum housing holding an aluminum circuit board all onboard.
The compartment in the fire truck, you can bang this thing as hard as you want with the K12s, because this thing is inside of the truck body, mechanically attached using aluminum and screws.
Anyway there is a lot of different types of compartment lights on the market, and I can’t say anybody builds a bad compartment light, but when it comes to FireTech compartment lights, we started with the design requirement. This thing will last for 25 years in service under a fire truck, on a fire truck or anywhere you put it.
Hey what’s up? It’s Sam from HiViz LED Lighting FireTech Lights. Today, we’re here with our freshly designed packaging and the FireTech 4X6 LED headlight.
The Perfect Headlight for Emergency Vehicles
Now this thing is super cool. If you haven’t seen them before, there are a couple of new features that makes this thing a perfect headlight solution for an emergency vehicle or first responder vehicle that makes it a little bit different than over the road vehicles.
So, first things first, let’s go ahead and open this thing up and I’ll tell you a little bit about what makes this thing so unique and designed specifically for fire trucks.
FireTech LED Headlight Kit
As we open the box, you’ll see this kit contains four LED headlights.
We’ve got two high beams, and two high and low combo beams. This thing looks super sick.
As we pull these things out, let me just set them on the table.
What you’ll see is:
This one right here, it’s got two pins, it’s a high beam – goes in the inboard sections of your fire truck
Then we’ve got three pins, that’s a high/low beam and three pins, that’s a high/low beam – goes on the the outboard sections of your fire truck
So, these two go in the outboard sections of your fire truck and these two go in the inboard sections of your fire truck.
Connect the Power Supply
When you look on the back, you’ll see the headlights have a “halo” wire attachment. These go to your marker light circuit or any of the park lamps in the fire truck. You just run that to a power wire. Usually, they are tucked right behind the headlight.
What Makes FireTech Headlights Special?
Talking about the headlight itself, “What makes this thing unique for a fire truck application?”
I’ll show you on the high-low headlight.
Angle of the Optics
It’s that when you’re looking at the fixture, these optics right here are angled down. So typically, when you look at the shape of a beam for a LED headlight, we’re going to project light further away from the vehicle to keep the drivers from fatiguing early while driving a long distance at night. Because a lot of times this style of headlight is used by the over the road trucking market, at night time on long hauls.
But in fire trucks, we’re responding typically in a different type of profile: We’re going 45 miles per hour or less on average (and we get it, you guys drive fast, but if you average it out, that’s the typical speed of a fire truck) and typically, it’s 15 minutes or less, so we’re not looking to reduce drive fatigue over a long distance driving at night.
We’re looking to illuminate the foreground and illuminate the area near the fire truck, so that when you’re pulling on to an incident, you can see all the things around the fire ground that are important.
So when you look at this headlight, this “half-moon” shape piece in the middle, that’s our standard DOT low beam and what make this unique for the fire service application is that we add these extra optics here on either side that tilt down a little bit and illuminate the area between the bumper and the bottom of that traditional low beam.
It’s not like we bring all of the light in. We’re actually adding more light in those areas.
What else is cool, if you look at this ring feature around the headlight, that’s a “halo.” That’s energized by this park lamp wire.
But one of the most unique features about the headlight is this thing on the back.
When you’re installing, you pull this little silicon vent cover off and this thing back here is called a GORE PolyVent. This is screwing in to the back of the housing.
One of the things that we found during the engineering of this product, was that fire truck headlights typically operate hotter than headlights used in other markets because when you pull on to a fire scene, you stop. That lack of airflow while you’re driving and the headlights are still burning, causes the pressure inside of most firetruck headlights to increase, because the temperature is hotter.
A hot headlight with high pressure inside eventually is likely to vent that pressure out between the little strands of copper in the wiring. In order to prevent that, we add this GORE PolyVent. That GORE PolyVent allows the pressure to equalize and it acts almost like a pop-off valve as the pressure increases, it blows air pressure out of that vent valve and then when it cools, it can allow ambient atmospheric air to come back through.
But what’s neat, is that there is a membrane inside of there that prevents water entering back through that vent valve. So, with this headlight, you’re never going to have to worry about condensation building up inside the headlight and, if it ever does, that vent valve is designed specifically to allow it to vent out right away.
With the FireTech headlight, you can take this thing out on the fire ground, you can let it get hot, and that pressure is going to equalize because we have a PolyVent valve. Once you get back to the fire station, even if you spray that hot headlight with cool water, it’s not going to get inside the headlight because that GORE membrane keeps the water from passing inside.

We’ve got a couple of really great demo programs where you can put this using your truck, run them for 30 days, try them out and see what you think, and then if you like, keep them, if not, send them back, we won’t even charge your card. Anyway, looking forward to doing business with you soon. Thank you so much for checking this out.
What’s up!? It’s Sam from HiViz LED Lighting. We’re here at the Firehouse World 2018 Show and we’re super excited to be here at this event. Thanks so much for having us in your city. This place is awesome, and we are looking forward to seeing you around the show. Come on inside and let’s check it out!
Hi I’m Sam Massa with HiViz LED Lighting in the FireTech Brand Lights. Today, we’re talking about the FireTech Guardian, which is our new Surface-Mounted LED Scene Light designed for the fire and emergency service industry.
2 Models for the FireTech Guardian Scene Light
Now this thing is pretty cool. We offer it in two models, a 10,000 and 20,000 lumen effective equivalent type fixture.
It actually makes about 6,000 and 11,000 measured lumens. I’ll talk more about that later.
What’s cool about this fixture is we designed this that it can passively dissipate the heat generated from the circuit broad. So you see this is really big heat sink. What’s cool about this part is that when you turn it on, we’ll only lose about 10% or 15% of the light output when the temperature of the fixture with just thermal saturation.
That’s unlike a lot of the fixtures in the industry that are really thin, they draw more power, produce more heat and the chips are affected by that temperature.
Features of the FireTech Guardian Scene Light
There are a couple of cool features to this part.
Number one, screws that hold this thing to the body of the truck and never touch the lens. From past experience working on an ambulance, a lot of times I have seen that light has a crack in the corner where the screw bolts in the fixture.
Screws and an Aluminum Housing
With our fixture this screw always touches the aluminum slug, not the lens, so you’ll never have a crack right in the corner where the screw holes sink with the body.
Another cool feature of the Guardian is the circuit boards are actually articulated down. So instead of having to take this fixture and mount it on a tilt, so that it shines under the fire scene where you wanted.
We’re able to move the LEDs, the boards and the optics onto an aluminum piece of the slug, so we can still get heat sinks in the backend of the housing. We get the optics, so light displays where we went on the fire scene. So when you look at our videos, you will see the light comes straight down the body and then projects evenly along the scene for really great scene like pattern around the emergency vehicle.
Last but not least on the back of this fixture, we have a part called GORE-TEX valve, so one of the things that happens when you turn a fixture like this on and there is airspace inside.
As temperature increases as the chips reach their operating temperature, the pressure inside this housing also increases. Without the GORE-TEX valve, you have a build up pressure which can sometimes cause the seals to blow out.
We’ve added that valve to allow the pressure to equalize inside this housing and then we allow for that to cool and contract, drawing in your backing without letting moisture pass through.
It’s kind of special membrane.
It’s coated the material, which prevents the moisture going through, so we can guarantee this fixture for as long as your trucks in service. Effectively a lifetime warranty on any of the products we build in the FireTech brand because of the few of those technologies.
Today, I’m going to introduce you to my friend Jack and we’re going to do some modifications to Jack’s head that will help us understand how light hits fireman’s eyes and how we can reduce glare on the fire scene.
Glare and Light Reduction for Safe Emergency Scene Lighting
One of the most common things that we get asked at trade shows around the industry is, “How do we reduce the amount of light that hits us in the eyes?”
Human Anatomy Lesson on How Light Impacts Vision
Well, one of the things that is really cool is if you look at Jack’s face here, you will see how his eyebrows up top and then his eyeball is sucked back into the socket just behind that area, so the anatomic shape of the human face allows the top of your eyebrow, your hair, and the fireman’s helmet to act almost like a sun visor and keep light at your eyes.
Now the problem is when lights are mounted low on a fire truck, they shine right into the face and that glare is something that a lot of times causes us problems on the fire ground.
The Solution to Glare
So how do you address that?
You can either mount lights higher on the fire truck on the body, you can mount them on poles or you can put them on light towers.
For every light on the fire truck, if we’re talking as a general package, then reduce glare by using elevation to your vantage as it is the best way to do it.
The Glare Test
Now what we’re going to do is remove Jack’s eyes and replace them with photometric light sensors, which is really cool. This little device can sense how much light hits this target.
My hypothesis is that as light goes up in the air, we’re going to see a reduction light hitting his eyes with more light or the same amount of light hitting the area where we’re working, which in fact reduces glare.
Anyway let’s see if we can quantify this, we’ll catch you outside.
Setting up the Glare Test
See you later eyeballs! Here we go? One eye down, one eye to go.
Looking pretty damn good as you ask me. All right, we’re finished, here we go for the test!
Now, Jack’s got two eyes, each one has its own independent light sensor. What this let’s us do is figure out how much light is actually hitting his eyes versus hitting him from the top of the head and being shivered by the shape of his skull.
The Testing the Hypothesis
All right, so we made it outside.
The way we have the things set up, is I’ve got pallet on a forklift with Guardian mounted in the front of it. That’s going to shine down and out all over the fire scene. This simulates the light, whether it’s on a body or up in the air.
On the ground, we have a sensor mounted on this turnout gear. This turnout gear simulates anything that is fire ground equipment. It could be chain saws or whatever.
The next thing we’ve got is Jack with light sensors in his eyes. What’s going to happen is this forklift is going to go up and we’ll calculate how much light hits the work surface and then we’ll calculate how much light hits the guy in the eyes and we’ll be able to identify what’s occurring on the fire ground to see if elevation really does make a difference in reducing glare, so let’s get this thing started.
The Results of the Glare Test
Now you can see a graph along the red and blue line, that’s the left and right eye. The green line, now with more light on target than the fireman’s eyes effectively shows reduced glare.
This is pretty cool how this all works. But what you’ll see is elevating a fixture definitely reduces the amount of light hitting a fireman in the eyes.
Testing Glare While Wearing a Hard Hat
In the next step, we’re going to throw a hard hat on Jack and see what happens.
The Results of the Hard Hat Test
Check this out. This is really cool. What you see here is where the shadow is now cast. His eyes are completely in a shadow, based in this little short brim of a hat. Now imagine it’s a fire helmet, it’s the same sort of deal. When you’re able to elevate the light fixture, use that hat brim to your vantage and you’ll keep light out of the fireman’s eye.
So what you’ll see here is a sharper cut off. Right there is where the light fixture changed.
Oops! I just walked over top of the sensor.
But you’ll see right here. This is the difference in light elevation.
We’re able to get such a sharp cut off using the brim of a hat, you’ll see here we’ve got almost no light getting the fireman in the eyes at all, meanwhile we’ve got an elevated amount of the light on the target.
That’s our goal.
Testing with the Baseball Cap
All right, the next step is we’re going to use a baseball cap and see if we can shorten this up anymore.
What I want to see is if we can make this steeper cutoff using that brim and making the time elevation shorter. So, the lower light fixture is the faster we get the cut off and that’s what I’m hoping for.
The Results of the Baseball Cap Test
Check this out! We’ve got almost no light hitting the fireman’s eye.
This is a very quick cut off and you’ll see it right about where the natural elevation the forklift. In almost no time we’ve gone from glare in the fireman’s eye to no glare at all in the fireman’s eye with more light on the target than the guy’s head.
What Do our Light Glare Tests Show?
What is this all tell us? Well, when you look at the fire truck scene lighting package, it’s more than just taking a scene light and bolting it to the side of the body.
What you really want to do is look at the total, comprehensive ecosystem and figure out:
do you have enough elevation
do you have enough body lights
do you have enough 12 volts
do you have enough 110 amps
The best way to do that is to use some other principles we’ve learned here using our lighting equipment in the lab and to work with experienced lighting consultants like ones at HiViz LEDs. Our team members will help to come up with a package that effectively illuminates your fire scene, reduces glare on the fireman’s eyes and helps you do your job safer at night.

All right. What’s up? It’s the HiViz LEDs FireTech team. I have in front of me the new FireTech Guardian and this thing is pretty exciting.
Today we’re going to do an unboxing of one of our newest emergency scene lights to hit the market.
New FireTech LED Emergency Scene Lights are Now on the Market!
This is the newest, latest, and greatest in forward facing LED emergency scene lighting. By forward facing, I mean anywhere forward of the panel, so it could be to the side, to the rear, to the front, but it’s not a blinking light.
So what we’re going to do is offer this product in two models.
Guardian and Guardian Elite
It comes in the Guardian, which is the 75-watt or the Guardian Elite, 125-watt. They’re in a same package, which is kind of cool, but they have different circuit boards.
Comparing the 2 Models
If we look at this packaging, the FireTech Guardian and Guardian Elite, you’ll see that come in two different models.
This particular box has GESMs. They’re going to be the higher output version and then GESM is the lower output version equivalent to about 10,000 or 20,000 lumen fixtures in the fire market.
We’ve also got our measured light output which is actually tested in a Goniophotometer, more about that later.
Anyway in the box comes this standard gasket and we’ll get to that in just a minute, but if you’re putting this on a truck where you might have had this thing in service for a few years, this retrofit gasket is something that will cover the overhaul of any other fixtures of similar size.
The FireTech Guardian Light Fixture
So without further ado, let’s go ahead and get this box opened up.
This is the FireTech Guardian.
As we pull things out of the box, you’ll see right here. These are the two body isolating mounting panels. Pull them out. Down here. We’ve got a set of components. This is the mounting screws looks like. Yeah, mounting hardware. Here we go. Four mounting screws. And then let’s go ahead and pull this light fixture. Set this aside. All right, so here it is. Here is our mounting gasket. Get those two separates all the way. I really like how they put that in the box. Kudos to our team for that one. Keeps it totally suspended, so it’s hardly get damaged in shipping.
An Impressive Prototype
Wow! This thing is slick. This is the first time I have actually seen the final production run. I’ve been messing with quite a few other prototypes, get little things changed and tweaked. I know our team has been working diligently to get couple of things like the optics and the holders on that stuff finished to 100%.
This thing is — it is seriously a lot different than the original prototypes.
I’m really impressed with the light at first opening. The lens is crystal clear. This material is made by a company called Covestro and Covestro materials are little bit squishy, so that if you hit something, it won’t damage the optics that are behind it.
However, the optics do no squish, they will break. So we added this Covestro lens since it’s got a high melting temperature and it’s got a little bit of good squishiness to it.
Whatever the term, the Covestro housing will keep the optics safe from any damage. This thing looks really slick.
Mounting the Light Fixture
So on the back side of this fixture, we’ve got this mounting place. This actually goes through the body, the durometer is a little bit lower than the original prototypes that we’ve shown a few times in the past. That lets us push a little bit more in the place and keep more tension on the bodies. This is pretty cool.
This is mounting gasket the fixture goes into, and then from there, it goes into here. This is the actual gasket interface. Sure the lines up and then that thing can be installed on the body.
This is actually a lot different then I thought it should be. It’s hard to do on the table because — cool, see at the bottom right here, these are two drain holes, so that if any moisture or water gets behind the fixture between that and the body, they will drain right of it which is pretty cool.
Then the fixture itself actually goes right in there. And that thing can be installed right on the body of the fire truck. This is cool.
So now we’ve got the light out of the package.
Actually look at the fixture, what you can see is we’ve got this crystal clear Covestro lens, the light circuit at the top. These two pieces are designed to give you light output from the fire truck that illuminates mailboxes and that sort of thing. These bottom two circuits are articulated down, so that’s lighting the area kind of midway in the fire scene. Then this bottom section right here, that’s lighting downside of the body and near the fire trucks that we have a light in the whole area near the outer ridge of the apparatus.
So this thing here is the FireTech Guardian fixture. The Guardian Elite has a little bit larger circuit board, but not a larger fixture.
If you actually look here at the bottom, you can see that those chips don’t have a primary optic on them, which is like a little silicon dome. And when you’re looking at these chips here, and if you compare them to the Guardian Elite, you will see that primary optic and then the upper chips are actually larger on the Guardian Elite as well.
On the center row chips, this is the same.
If we do change the optics depending on where the design, so this guardian fixture is specifically just posted on back of the ambulance body or on the side loading doors, we recommend that in areas. We’re looking to reduce the glare for the visibility and then, for other areas we’re just looking for total scene lighting coverage. The Guardian Elite fixture, with a bigger bottom and top row chips, gives you a little more light output, which just flood the area.
Test the FireTech Guardian Light Fixture on Your Emergency Vehicle
Anyway, this is the FireTech Guardian fixture. We’re super exited about releasing this to the marketplace.
If you want to get a copy yourself, we’ve got demo programs to try them out. We’re recommending doing six on an ambulance for 30 days. You can do Guardian or the Guardian Elites. The Guardians typically plug right in. They are 75 watts, so they don’t require much change to the electrical system. But the Guardian Elite is 125 watts, so the worst case scenario is a need to upsize your wiring.
Welcome to REV Summit 2018. I’m Sam from HiViz LED Lighting’s FireTech brand and we are super excited to be here this event.

FireTech products are often imitated, but never duplicated. With close to 70 patterns worldwide, we’re proud of the ideas we come up with. Fortunately, competition breeds innovation and we’re eager to see our company rise to the challenge.
Stop by our Booth at FDIC 2018 to see how we’re working to continue to push the envelope and improve the safety of firefighters worldwide.
Some History of HiViz LED’s First FireTech Scene Lighting Product
The very first FireTech product was actually installed on a REV Group E-ONE fire truck about 7 years ago and since then we have really grown a line of business and in the development of our product range. It’s been a real pleasure working with all the REV Group brands since the inception of the FireTech brand, really growing in E-ONE, KME.
New HiViz LED Products are in Development
Now we’re doing some work with Ferrara and we’re excited to be working now with the endless divisions. Part of the 2018 focus is going to be developing out the product range specifically geared EMS marketplace and the REV Group, of course, we know the champion in that area.

All right, so here we are standing in front of Ontario California’s new tiller truck.
It’s a pretty interesting history regarding the design process for how we came up with lighting package used on this truck.
A Quest to Find the Right Emergency Lighting Output
So a couple of years ago, here at this show, we met the guys from Ontario. We discussed ways to create the optimal light output needed for a safe and efficient working condition.
During the process we began talking about how to create more lighting in specific areas that they need in front of a truck, so we started with a 72 inch FireTech brow light.
Fine Tuning the Solution for Emergency Scene Lighting
As our conversation evolved, they began asking other types of design questions that really helped us craft the right lighting apparatus for their newly designed fire truck.
How HiViz LEDs Creates Scene Lighting Fixtures
One of the things that HiViz offers is the ability to design a truck digitally, before it is every manufactured. This is done so we can recreate where the light falls and know exactly how much light is going to fall in any given point inside of the truck.
This is called a fit-out guide. For the Ontario Fire Departement we started with the KNE 2D drawing of the truck.
A KNE 2D drawing is what the truck manufactures uses for fits out when they’re configuring compartments and other truck features. Then our team took the 2D drawing and created a 3D rendering of the truck. We do this so we can represent how high and how wide the truck will be. From there we can fine tune which fixture would be best for optimal output.
For example, we could say, “okay, let’s try this fixture with may be 10-degree optics, now let’s try with 60-degree optics” then we are able to tweak the optic pattern for each fixture whether it be for a brow light, a side-scene light or even up on the aerial.
You will see the tip in tracking lights, the side scene lights, the pole lights and other fixtures. We change each one of the parts until we find exactly the right amount of light in every area near the side of the truck. Once we are done, we are able to guarantee NFPA compliance as well as maximize the light the customer is looking for different areas around the fire ground.
No Cost Video Analysis for Our Valued Customers
Now this video-guided process is something we do at no cost for our customers. No matter where in the US your truck is being manufactured, our team is happy to provide you with the 3D video analysis so you can have the right light fixture installed at build, instead of retrofitting after the vehicle is on the streets.
Give FireTech a Call for Emergency Lights on Your Next Fire Truck
