I have seen a body tube extender on eBay for the "e" series Surefire, which allows you to run 3 CR123s in a L4. I know that this should work fine with an KL1 as they have a voltage input range of 3 - 10 volts and so should just result in longer run times, but has anyone tried three cells in a L4? Would I get extended run times or am I likely to fry it? [img]/ubbthreads/images/graemlins/eek.gif[/img]

Any help greatly appreciated...
