I'll post some beam shots soon. I'm running a Shark driver. Noticed that I could not see any more brightness above 660ma, so I limit the rotation of the potentiometer accordingly. The optics are from www.[B]futureelectronics[/B].com/ (Polymer Optics). Tried the spot first, but ended up using the medium flood. The power connector is from a monitor cable, BNC type. Made the mount from 2" round stock. It is designed to attach to my 31.8 bar, right next to the stem. She sure is bright...but I have not got a chance to do a shakedown ride.
