Another possibility is to use a non-dereelight XR-E EZ900 P60 pill (light engine) that will run at full brightness on a single 18650 (or single RCR123/16340) li-ion battery. I have a 2.1 amp one made by vinhnguyen54 from CPF Marketplace, and some of the other drop-in specialists may also sell them. It works fine in my Dereelight DBS with an aspheric head, but I don't know about the DBS-T with its twisting head operation.
Not the one I have.This would work fine on 2xcr123a as well, correct?
Other pills may be higher voltage - you'd need to ask the maker.Runs at 100% on 1 18650. Working voltage range is 3-4.5V
Has anybody here tried dual 18350's in the CL1H tube? You get the voltage of double cells, with better runtime than 16340's. I would love to try it, but my 18350's are on delivery, kinda hard ordering these type of cells, not too many people (and lights) support them.
I ordered a few of these for the Dereelight and my Crelant 7G5 V2 (w/o extender). Can't wait!
If I have time, I will test the 18350 IMR tonight.
