I have seen a few people complain that the H502 has amazing output but no optic to contain that output. Tonight, I had an idea and would like to share it.
Instead of trying to shoehorn in a reflector on the H502 to give it a little more distance and a little better use of all of that light, what about using a Fresnel lens? I was messing with my iPhone and noticed that the LED in the phone had (what appears to be) a Fresnel lens over the LED. It has a defined hotspot with a decent amount of spill. In fact, the spill has the biggest viewing angle of any LED system I have seen. I'd put it at 180 degrees.
If anyone has a Zebralight H502 and a small Fresnel lens, you should combine them and show the results.
What do you think?
