The Safetran unilens signals don't use LED's, but fiber optics.The two aren’t incompatible, but it looks like the illumination is some sort of incandescent bulb from this photograph.  I’m using the reflector as a guide, though it is amusing from an engineering point of view to find the light spread out, only to be collimated again by the fiber optic adapter. LED laser direct to fiber next time? |
