That was my question. If anyone knew if a simple led swap on a new pill would net any good results. The led this light uses is the xp-g2. I seem to have read somewhere the xp-l is a brighter more eficcient led on the same size die. I could be wrong I'm going off memory. That was all my logic was. I could spend $40 on a pill and led and if it don't work any better then I've wasted $40 and i go back to the original pill.
