i have an array of 17 white nichias in parallel hooked up to 3 nimhs. the nichias are from various sources, basically all of the white leds i have left over from past experiments.
the thing is, after about a minute after closing the circuit the leds start to pull 900mA @ 3.55V. that's 53mA per led!
i'm curious why the leds would pull so much from a 3.6V power source. is it something about hooking so many up in parallel or something? i wouldn't think it would pull this much unless i drove them to 4+V.
would this, over time, damage the leds and reduce their half-life? i would imagine it would, but i remember something about over-voltage killing leds faster and these are technically at voltage specs.
