Sorry I didn't reply sooner. I modded mine last summer (July?) with a high-cri xp-g from Illumination supply (this), and it works great. If I remember correctly, it was a little tricky trimming the mcpcb to fit and to be at the right height, but it's certainly doable. I used arctic alumina adhesive to attach the LED. I think I turned either a quarter or a pre-1982 penny into a little copper heatsink for it, but I can't quite remember. Good luck all.
