thanks everyone.
and yes asdalton, that's the one that you sold to me (and the dorcy AA should be fine, read on /ubbthreads/images/graemlins/tongue.gif )
i did have a chance to test the ultra G and dorcy AA in fresh batteries last nite and that made a difference.
with a new alkaline (as least i thought it was), the dorcy AA output is still way lower than my ultra G with a used NiMH. (maybe it was a bad alkaline)
after that, i tried them both in a pair of fresh NiMH and the output comes in much closer to each other. with the fresh NiMH, the dorcy gives out a much better output, close or as least the same as the ultra G. i was sleepy /ubbthreads/images/graemlins/sleepy.gif and couldn't remember which one is brighter. but they are close /ubbthreads/images/graemlins/tongue.gif
anyway, here is my take on it. at a lower battery level, the ultra G gives out a better overall output cause it only needs to drive a single LED (vs docry AA needed to drive 3 LEDs, and less efficient internal?)
oh and i agree, the dorcy's are relatively inexpensive. it wouldn't bother me too much if i lost or broke a dorcy. but i wouldn't want the same to happen to my ultra G. i am more emotionally attached to it. /ubbthreads/images/graemlins/grin.gif
(ps. how to open up a dorcy AA? maybe i can do *something* to the reflector /ubbthreads/images/graemlins/tongue.gif )
