Yeah, it almost has to be something like that. It's interesting that the L2, a high power LED, and the A2, Xenon with three low power LEDs both overheat and they both have electronics in them.P95Carry said:That crossed my mind Ron - not just hot bulb but maybe too a poorly heat-sinked SCR or power tran'.
OTOH, the Streamlight TL2 LED, TL3 LED, and the Inova LED have electronics also and they only get warm over the entire discharge time.
Actually, as I think about it, it seems more like inefficient power control that generates more heat than the heatsink/case can handle.
