BugLightGeek, I will try to take some beamshots if I have time at night. As a 3*1W, it's very bright, brighter than my another 3*1w. However, since it's cyan luxeon, I think it's less useful than the 3*1w white luxeon.
LEDmodMan, that tri-sink is made by another cpfer - Xminxm. He can tailor-make the tri-sink so that I was allowed to used the reflector. However, I used the optics finally.
