I have Lightforce XGT's with clear combo covers. I've been thinking about getting some crystal blue combo covers. Are they any good? Are they better than the clear covers?

im guessing here..


depends on the environment you travel in.

eg... amber lights work in fog

red light/blue light works in snow etc

red lenses are excellent for hunting foxes. It keeps their attention for that 1 or 2 seconds more. Just perfect for those head shots :armsup:

As for the blue lenses I haven't seen them in action, but I assume they have the same effect as the blue bulbs?? I noticed a few kicking around Landcruiser Mountain Park the other weekend.

Most of the trucks i see that are running light force also seem to run the blue covers, if the truckies are using them they must do something?? or they could be cheap :)

Using a lens to change the colour of your lights reduces the total amount of illumination you get, because all it is doing is filtering out some of the light of other colours.

Yellow, blue, or any other colour of light is no better in fog than white light; using yellow is just a tradition.

Genuinely blue lights - ie where the (xenon) lamp itself casts a blue light, as opposed to a filter making white light look blue - are a different story though. There is no loss of light from making them blue, the light itself has a bluish cast. Note that there are these genuinely blue lamps and then there are ordinary halogen lamps that have a blue tint on them. The tinted ones are just a fashion item.

So the short answer is that if you have xenon lamps which are bluish, then great, but if you have ordinary lamps, which are yellowish, there is no point in tinting them blue, and all you achieve is to reduce the amount of light they put out.

I have a patrol with crystal blue XGT's and relayed 90/100 H4's I find there is a slight loss of light output, but bearing in mind the power of these lamps the difference is only marginal, I find the colour temp slightly higher (ie the light is white, not that little bit yellow that halogen create) This colour of light i find easier on the eyes and more comfortable to use in the rain not as much glare is reflected.

was just about to rebutt you based on my poor high school physics memory but a quick google search gets a fair few hits

http://www.gi.alaska.edu/ScienceForum/ASF5/593.html
http://www.newton.dep.anl.gov/askasci/p ... y99xx4.htm

It is seams that thet scientific community have trouble proving any difference but there is many highly educated people that can offer a fairly sound aurgement that they should work in a perfect world.

although my experience is that yellow filtered light in very heavy fog was much eaiser on the eyes maybe it is just the reduced power from the filtering (low beam vs high beam in fog) ?????
