On Gerber's site, Key Features says "3 LEDs." But Product Description and Technical Specs both say 1 LED. You can't tell from the picture, but QuickBeam's TX review states and shows a single LED: http://www.flashlightreviews.com/reviews/gerber_tx3.htm
Could such a disparity be explained by the Luxeon lottery? By slight differences in LED mounting? or by both? I'd like to think that I can buy a TX and have a chance at getting the brightness that Quickbeam measured for the LX.
