Greetings,
My key chain flashlight (Thorfire TK01) is a single AAA unit with Nichia 219C LED. I’m using a 10440 Li-Ion battery instead of the AAA. I’ve pulled the 219C datasheet. It looks like 3.6V is the maximum this emitter can take. Anyone know if the emitter will tolerate the Li-Ion battery?
For whatever it’s worth, the light is crazy bright with the Li-Ion battery. It’s really quite impressive.
EDIT: I should have mentioned that heat seems make it away from the emitter, the unit warms up quickly.
Thanks
