When it comes to getting the best bang for your buck in an LED reverse or camp light, there are two main things you need to consider before forking over your hard earned cash. Firstly, the light needs to be placed in the right spot, and secondly, you need pick the right beam pattern in order to illuminate the things that are important, which is what you can see in your rear view mirrors.
To put this to the test, let’s take a look at two different beam patterns, the Rigid Industries SRQ2 driving pattern, and the diffusion pattern in a side by side test. We used a variety of different mounting positions so you can see just how much difference beam patterns and positioning can make.
To start with, we mounted the lights down low on the centre of the rear bumper. As you can see the centre of the rear bumper is by far the least effective spot to place a light.
Next, we moved the lights up to the centre of the roof rack. The first thing you notice is the hotspot of light right behind the car has disappeared, and the lights are producing more even spread. Once again, the driving pattern displays a sharp drop off in light out to the sides where it is really needed.
Now, let’s take a look at what happens when we move the lights into the corners of the 4x4 instead of in the centre. First, the lights are mounted in the corner of the rear bumper. While both lights look much better here, the driving pattern is really creating a nasty hotspot on the ground. The diffusion pattern does a much better job here, as you would expect from its ultra wide beam pattern.
Lastly, let’s see how the beam patterns compare when the lights are mounted in the position we think is the best spot – mounted up high on the corners of the roof rack.
These results highlight that the driving pattern is simply the wrong choice for a reversing or camp light, but the diffusion pattern on the other hand is simply perfect. The diffusion pattern not only provides clear light in a wide pattern from side to side, but also from top to bottom, which is equally important!
It’s not hard to see now just how much difference it makes positioning
lights correctly, but also how important it is to select the correct beam
pattern for the job
