I've wanted to do this mod for a long time, and initially I wanted to use an SSR-50 emitter, but it just wasn't feasible when you consider the size of that emitter, plus the current it takes to make 500 OTF lumens with it. Fortunately Cree recently released their new XM-L emitter, which fits the bill nicely for this type of mod. Anyway, enough jabbering and on to some pictures.





All of you should know what a 123-2 Quark looks like, but here's a pic anyway:





















First things first, get the little Quark head naked .



















Trim the centering plastic piece to fit the larger XM-L emitter:



















Open up the reflector to fit the larger XM-L emitter:



















Test fit the parts. Looks good:



















The MCPCB must be buggered up to make this work:



















Prepare the driver:





















Solder leads. Please excuse the messy solder job, I'm in desperate need of a new tip for my iron...........





















Insert pre-fitted centering piece:





















Put everything back together so that it looks untouched :





















I'll try to take beamshots of this mod when I have time, but until then, the beam has much more flood than the original XP-G beam, but it still appears much brighter to the naked eye .





My OTF test results taken in my homemade 16 integrating sphere are as follows:



This light is powered by a single AW 17670 protected Li-Ion battery, and it was fully charged for testing.
