180° floodlight lens

Anyone have an idea where I can find a lens to mount over a Cree that will allow it to flood. I would like to mount it on the end of some 1" square tubing that has been capped. Waterproof would be nice.

i would recommend using a seoul instead of a cree if you want it to be a floodlight. it has a wider beam angle out of the emitter that is pretty close to 180 degrees. then you would just need to find a suitable cap for it and seal it up with some epoxy or silicone. i'm not sure how nice this has to look, but i've used the clear bottle caps from water bottles with good results. the screw on kind will cover an entire star, and make a good diffuser to boot! oh, and cheap too.
