Yeah, been running it at (1 amp which is around what the lantern draws) for a while and itâs not very hot. But does get hot at 2 A. If itâs a constant current driver, the current is higher on low battery. Has anyone done runtime graphs yet?
edit: maybe the heat path of the whole thing is directly connected there, since it looks like the whole bottom piece is part of the same aluminum block. The tailcap is just the only place without plastic molding.
I let the light run a couple of minutes with just the usb power connected (no battery) and the tailcap got warm (hot after 10 min). Itâs the led and driver heat flowing there. Combined with the battery and spring heat, itâs no wonder then. The whole battery compartment seems to be the led heatsink as well.
I already showed my interest before but since I changed my user name I want to be double-safe to get on the list for the next batch Thanks for your efforts Freeme!
