If you call Tigerlight, they recommend leaving it on the charger all the time as long as it's used once every couple of days. The only thing you have to really remember is:
1. Never let the sucker die out. As soon as it starts to dim (even the slightest bit), turn it off and charge it.
2. Never turn on the light while it's in the charger. (this according to TL)
If you don't use it for days, I would personally take it out of the charger after 24-48 hours. It's still insanely bright after being off the charger for a week. /ubbthreads/images/graemlins/cool.gif
BTW, it's not a dumb question. A dumb one would have been, "how do you turn on the light?". /ubbthreads/images/graemlins/wink.gif
