I've never heard of a 3-led 2aaa M*g mod, though you could do one. Joule Thief sounds like a reasonable approach. Just select the leds to have very similar forward voltage.
hmm........... i could do that, but the jt would add so much havoc, the tail cap would have to be wired, oh man. maybe some other time. damnit, i need a converter that will take 2 AAA input and put out 90ma @ 3.6v. (3x30ma...)
any ideas? i want something that can fit within the original spot and use original switch. i could just direct drive, but that's no fun.
A Lambda micro converter should be able to fit in there, and it provides enough juice to run a Luxeon at reasonable current. Expensive though. What's your attachment to the Mag 2aaa? Anyway, look at the Tektite LT-1, which uses one led. It fits in the regular minimag bulb socket. Maybe you could set up a JT circuit like that.
