Command Light has recently began a few studies to determine effectiveness of scene lighting.  Not only does this help us build better, more effective products, it also helps you determine the best products for your department and jurisdiction.

We have used advanced software that measures light intensity and fall off and have inputted many different models and types of light.  This study was done to help determine the best placement for lights to give  more useable light where emergency personnel need it most.  Browse through the images below and see why we choose to keep the light source closer to the scene.  This study compares 3 different lighting solutions all using the same LED light heads.  One style is a tower that contains 6 LEDs located in middle of truck 10 ft above roofline.  Another is a of 6 LEDs in the middle of the truck 30 ft above the roofline.  The final system contains (4) 4 ft poles with 1 LED each at each corner of the truck.

Birds Eye View

A full view from above that gives us perspective of how intense lights are at different distances from the apparatus that the light sits on.  Click on each picture for a larger view.  Each arc represents 10 ft.  The vehicle is roughly 20 ft from the edge of the apparatus.

Light Output of our CL602 is shown on the left.  This tower consists of (6) 150 watt LEDs that output 15,000 lumens each.  We chose these lights because it closely compares to other lighting options available.  Useable light goes to distances of roughly 58 ft.

The light output of an average mast style light is shown in the middle column.  This mast rises 30 ft from the top of the truck and  is equipped with  the same (6) 150 watt lights that are consistent with the CL602.  Notice the useable light only reaches about 45 ft.  This is because the higher the light source is in the air, the less output you will have at scene level.

The light output of a set of pole lights with (4) 150 watt lights on each corner of apparatus is shown on the right.  The useable light goes quite far due to the fact the light source is near the scene, but the intensity of the light is quite diminished because of the limitation of 4 lights and having different locations of each individual light.

View of Interior of Vehicle on Scene

A view of the interior of a car on scene.  Created to give us a real world scenario to see how much useable light are inside vehicles and if it is affected by the angle of the light source.  The vehicle is roughly 20 ft from the edge of the apparatus in which the light source sits atop.

The CL602 (left) shows even lighting throughout vehicle and illuminates to levels comparable to the interior of a restaurant.

Mast style light towers show similar lighting to the CL602, although parts of the interior are under more shadows due to less intensity and the fact the light is coming from a higher angle, causing more shadows.

Four Pole Lights show show considerably less intense light inside the vehicle.  This was expected with the smaller amount of output produced by the lights.

The CL602 (left) shows intense light for much of the scene, that of which you would see in a hospital examination room.  This light continues up the side of the car.

Mast style light towers also show a good combination of light that expands out and away, but lacks the intensity at scene level due to the distance from scene to light source.

Four Pole Lights show considerably less useable light than a permanent tower light of some kind.  Not only is the light not intense, it covers a significantly smaller amount of the scene as well.

Our Concept on Towers

This data helps us confirm that Command Light towers are the most versatile towers on the market.  We conclude that any type of permanent tower is a much better option than portable lighting.  The power needed to reach deep into scenes is only prevalent when a tower is able to generate a higher lumen output from a single source.

We also conclude that it is an advantage to keep the light source closer to the scene as the intensity of light begins to reduce as the source gets further from the scene.  There is a happy medium that is up to debate as you do not want to keep your source so low as to prevent large shadows from the apparatus, but not so high that you begin to waste valuable light and inevitably will need to generate more power to create useable light in the area of need.

This is why we love the fact that Command Light towers have the ability to be moved in countless positions.  No matter the scene at hand, a single tower can be positioned to work differently in all types of situations. If you need to prevent shadows right up against the apparatus, the tower has the ability to overhang over the topline of the vehicle.  It can also be adjusted depending on how you want the light to go, if you want more intense light 10 ft from the vehicle, no problem.  If you want it closer to 30 ft from the vehicle, its just a push of the button and seconds later, the center of beams of lights is concentrated exactly where you need it.
