I wish I had written down the bin of the luxeon in my Dorcy 3xAAA before I accidentally demolished it trying to get it to work in a Dorcy 1xAAA. I think that it was SV1J, but I really could be very wrong. I remember the 3xAAA hotspot impressing me so much because it was noticeably brighter than my XM-3 when held side by side. The color was warmer than the more blue XM-3. I still hope to get to use that big Dorcy reflector for something good in the future.
I don't want to go out on a limb, but I think that the hotspot on the Dorcy 3xAAA would even beat my QIII with the 20mm IMS smooth reflector on primary cr123 (I don't have rechargeables yet).
I just tried to measure the Dorcy reflector. The effort was hampered by the fact that I can't get it out of the head of the flashlight, so a margin of error will exist. I came out with something like 28mm wide and 23mm deep versus the IMS relector for my QIII at 20mm wide and 15mm deep. That seems to me to help explain the Dorcy's very respectable beam. Still, though I going only on memory from a couple of months ago about the Dorcy 3xAAA being lit up.
Man, I thought I was going to be helpful, but I'm afraid I just muddled things more /ubbthreads/images/graemlins/frown.gif
