Stats of TVL1:
-Body is 2"x2"x1" block of Al, ~2mm-deep fins dremeled in, three 1/8" holes drilled in
-Finish is black paint for emissivity
-4xCree Q2, 2S2P
-2 "Kennan" drivers from KD, 2P
-755mA to LED (according to KD)
-~1A draw from 8AA alk or 1x12V SLA
-Connectivity is a 12V cigarette lighter plug, serves as switch
-Diffused by Glad Press'n Seal
-Drilled and tapped for standard tripod mount
-Washer just added under bolt head, not shown in pictures

Stats of TVL2:
-Body is 4"x4"x1" block of Al, fins machined by my friend (Sasquatch1985 on CPF)
-Finish is Sharpie on rear of block for emissivity
-11xCree Q2, 11S1P
-1Ω, 10W current-limiting resistor
-0.6A draw from 3x12V SLA (same battery as HMM)
-Connectivity is an old AC power cable with female quick-connect terminals for SLA blades
-Switch marked with "O" (off) and "|" (on)
-Diffused by Glad Press'n Seal
-Drilled and tapped for standard tripod mount
-Washer just added under bolt head, not shown in pictures

Future builds of these will be mounted to pre-fabricated heatsinks, as that was a big part of this process. Also, the resistored TVL2 was much easier to make than the double-driver TVL1, so I'll probably stick with resistored designs. I hope to use these on my video shoots during this quarter.
Since I took the beamshots, I have reapplied the Press'n Seal to give more circular beams instead of the slightly tall, oblong ones shown.
