Like most people I guess, I was under the (false) impression that driving lights, or spotlights were pretty much all the same. I took the time to talk to the team at Britax earlier this week and I can tell you that there is quite a bit of difference between some of the leading brands.
To put it into basic terms, there are three main aspects to consider with lights.
Firstly, the bulbs which are usually either QH (Quartz Halogen) or HID (High Intensity Discharge). Obviously, the HID provide a 'better' light.
Secondly is the reflector. A high quality reflector will give a good light.
Thirdly is the lens. A quality optics free lens is the best.
What some leading brands have done with their lights is to build the light refraction into the lens which isn't a bad idea. In short they use optics in the lens to re-correct and spread the light pattern. An example of this can be found in the Hella range.
Some other brands actually use a 'clip on' filter to achieve a similar result, however a filter will actually block some of the actual light. An example of this can be found with the LightForce brand.
What Britax do with their lights is build the refraction into their reflector (free form reflectors) and then couple this with an optics free quarts glass lens. By doing this, the light from the globe (either QH or HID) is being used in the most efficient way possible (by use of the reflectors) and then travels through a clear, free lens which allows for no distortion of the light.
This description above is really in its most basic form and to really appreciate how much of a difference it really makes, you have to view these lights side by side. By viewing them, I mean get them working side by side with exactly the same components. Ie: bulbs, power input, etc.
I took a night out this week and attended a talk that the team at Britax did with the Townsville TJM staff and after hearing how it all worked, we were then shown what it all looked like. The difference cannot be explained in words other than bloody amazing.
I currently have LightForce on my Cruiser and have been pretty happy with them, but I am now upgrading to the Britax XRay lights and can't wait.
Take it from me, I am not an expert when it comes to lights but if you are thinking of getting a set of driving lights, then check out all the brands and put them up side by side in an equal environment and the proof will be staring you in the face.
