I ordered some glow in the dark powder from http://glowinc.com/ This is unnecessary, but a nice touch, when you seat the Led, there's a bit of room around it and the reflector, someone at candlepower forums came up with the idea of filling in around the led with epoxy laced with this powder, it continues to glow after the light is shut off, making for a nice effect and a find in the dark aid for the light.
