Does anyone have any first-hand experience with the XM-L P60 drop-ins at 2.8-3.1A? With other LED modules running at these levels there were numerous issues with the lack of heatsinking in the 6P-P60 design. I know the XM-L P60s are just being delivered but I wonder if overheating/output loss is a big problem or if usage is just limited to short periods at full power.
I know bigchellis' testing showed output to drop quickly in the P60 design if the module wasn't designed with a substantial heatsink. So far none of the modules I've seen appear to have any more heatsinking than the standard XR-E pill. I find it curious that XM-Ls are driven at similar levels in P60 modules and heavily heatsinked lights such as the ThruNite Catapult (which even has overheating protection).
Just wondering if the initial output advantage of the XM-L in 6P-style light is maintained after xxx minutes.
