i just picked up the twin pack (1, 3AAA & 1, 6AAA CREE flashlight pack from Sams club a few weeks ago and thus far have been impressed with the light / price ratio. has anyone else checked these out? i've modded my big one a lil with some GITD next to the emitter, but am interested in any other mods some of you have done. i had to unfortunately pry the lens cap off to get to the internals, it seems to be a snap in place type of lens/emitter assembly. any advice on how to avoid this technique? i also noted that the control assembly seems to be mounted in the end cap, to control the brightness (low, high & strobe) it seems that the control circuit actual strobes the LED @ a high rate, is this normal? any and all advice is welcomed, as i am newish to the LED field. my exp is in the HID area but have been impressed w/LED tech as it has evolved quite a way.
