I have an amber LuxIII in a 2-C Mag modded by 3rd_Shift, and a red-orange LuxIII Aleph 3 built by McGizmo.
They both work really well (a lot better than incan), but the amber works better than the R/O.
I think the reason these lights work so well is backscatter. Longer wavelengths (toward red) tend not to have less backscatter. Some of this is due to physicsa nd some is due to the way the human eye works.
I can go out in the fog and light something up with a white light, but the fog in between me and the target is lit up as well. When I switch to the R/O Aleph, very little of the fog is lit up, but the target is nicely illuminated.
The catch with red is that your eyes are not very sensitive to it, so they act quirky when you are trying to see with red light. You can't see red light at low intensity as well as you can other colors. So, when you illuminate something in the distance with a red light, is seems very faint compared to colors like green or blue.
Red penetrates fog better than the other colors, but you can't see it as well.
Amber seems to be the optimal color to use. It has a reduced backscatter compared to white, but your eyes are much more sensitive to it than red. I have gotten my best results from amber.
