Man these LED's have a low VF! I've tested 2 LED's so far XML T6 2T and TD. Both have basically the same vF till 3A, then the 2T takes the lead. 2D had a vF of 3.250v @ 5A.
My test setup: BK Precision 1744A
Heat sink: Designed for Intel Q6600 CPU (95W)
DMM: Calibrated Fluke 179
1A - 3.000v
2A - 3.103v
3A - 3.147v
4A - 3.177v
5A - 3.218v
Cree datasheets state 3.000v @ 1A, 3.241 @ 2A, and 3.337v @ 3A.
