I built this circuit to drive a 1W LED and placed the whole assembly in a maglite. Everything works splendidly accept for one thing: If the flashlight gets jarred or dropped, the light will turn off, but the circuit still keeps on sucking current. I think there is a connection inside the flashlight that must get disconnected for a very short time, but still throw the circuit off. If you turn the flashlight off then back on, everything works fine. Sometimes though, when you turn the flashlight off then back on, the LED will come on for a half second then turn back off.
I tried using a 120 uf capacitor instead of the 22uf supply capacitor for C1 and this didn't make any difference. Space is a large concern so I can't really use any capacitor too big.
Any ideas to fix this? Thanks :lol:
