I want to use a BB800(actually 833), TWAK emmitter, on one 123 cell in a McLux. Will my runtimes be short and not worth it? If yes, any suggestions on how much current I should run for the Lux3? I want as much blinding light I can get off one 123 with about 1+ hour runtime if possible. Sorry I'm not very good with math. Appreciate any help.
