I was messing around with a Nichia 083 LED the other night, going through the optics box and trying it with various different reflectors. It does not seem to play well with most. One of the reflectors I tried was a 2AA mini-mag reflector that had been bored out to about 3/8" for some experiment. Placing it in front of the Nichia, I got a good looking hotspot focused in an even field of spill. I need to do some further work and probably cut down another reflector to really optimize the focus but I thought others working with the 083 might be interested.
