This Sofirn SP31 is a nice 18650 type light to give to muggles. USB charge port, 600 lumen, 3 simple modes, and a decent 18650 cell. 600 lumen is really quite a bit of light for someone not used to retina blasting hotrods. The light doesn’t really get hot on high for any length of time.
I tested a double wrapped protected NCR18650GA, and it fits fine.
Personally, I’m not a fan of the XP-G3 emitter, so I changed it out to a Nichia 219C 4000K emitter on a M.E. 16mm MCPCB. Although, the XPG3 is ugly shining it on a white wall, it’s really not bad at all outdoors. If I was giving one away, I wouldn’t bother changing the emitter.
Nice light with a Sofirn 2200 mAh Cell.
Side button light comes on for a few seconds when turned on, and blinks while charging.
Easy to get apart. At first I thought it was grease on the bezel. Turns out it’s glue that never hardened. Twisted it off with my hands.
Remove XPG3 MCPCB, and remove centering screw.
Install new Nichia 219C MCPCB from Mt. Electronics, and done.
