Thanks O-L! Perhaps in the future. I might pick up another 1 or 2 in the meantime. I am getting backed up on my mod projects and am finding that I just don't have the time for flashlight mods during the summer! (Too much work to do on the house, the yardwork, etc, etc. . . ). The lawnmower headlight mod comes next!
If I'd use an 8x7135 driver, would the 4th cell be wasted? Is there a better suited driver for 4.8 to 6.0v use? I could see this being a good setup for a non-flashaholic's use.
