Sale pending to Gebe. PM sent.

As far as cells for this light, I think the guys have described what is necessary. I used four NCR18650GA. They work great because they have the necessary current rating plus the top is slightly raised. Flat tops won’t work in this light. The button top Samsung 30Q’s would work just fine too. I think the Panasonic NCR18650B protected with button top would work on all but the highest level. By that I mean those cells may not be able to source the max current. I have 4 Keepppower 3400mAh cells and I’ll give it a go and measure the output. I know I was getting just a little over 5000 lumens in my makeshift lightbox on the GA’s.
