It’s not 20700, ⫹ ACTIVE AGAIN ⫺ JETBeam TH20 ✺ Tactical flashlight XHP70.2 - Interest list but if you want 3,450 lumens why not consider 20700/18650 sleeve and format the 2-CR123A isn’t even going to get it warm. I’m asking manufactures on their Facebook and their web sites to consider the extra power added by the new size. Granted the 20700 is only a tiny fraction of 1% of the batteries but so are their small cutting edge super bright lights. And that’s my rant for the day.
