well, traditionally a madmax+ q3l would probably be the brightest, but if you can bribe/talk/threaten/blackmail/beat this you'd be one of the luckiest guys around! /ubbthreads/images/graemlins/grin.gif
Brightest but maybe too big or expensive: L4.
A little smaller and less expensive, Arc LS (if you want that brightest that would be a LSH-P) /ubbthreads/images/graemlins/grin.gif
And for a AA Mag size try a MM+ with R2h/R2k.
Re: whats the brightest led light the size of a aa
My L4 till I got my McModule (5/w replacement LED) from Mr. Bulk now my Pelican M6 is the brightest but it is a bit fatter than the minimag and slightly shorter.
