Help with a project for a noob

Hi everyone,

What a great site, I finally found a support group for my addiction! I love lights and this site has got me willing to experiment. I have a light that I would like to mod. It is an X-glow ALC-0212C http://www.favourlight.com/1/?products/print/ALC-0212C It has a XR-E diode and runs on two c cells and is rated at 136 lumens. It had a cheap plastic reflector which I replaced with the OP reflector from my Tiablo MA6. That change added to throw and I would like to get some more brightness out of this light. I light the C cell format but understand it made be a limiter for voltage. The light is regulated but I can't find at what voltage.

My question is can add more voltage safely by building a carrier for a single 18650 ( I have a lathe and a mill) or will I cook the driver. I am very skilled in the shop but am new to electronics. :) any ideas would be most welcome. I have read the sight for teh last two nights but can't find anything on c cell lights.

Thanks

Jim
