I just won this exact torch from Crelant. The only way you’ll get maximum lumens is to put in a 14500 with a AA dummy cell. Two lithium primarys are bright but far from 400 lumens in my guesstimation. And why put in 14500 and dummy?…. It will cut total runtime well over 50%.
This is a nice little light with 2 lithium primarys or alkalines . Nice and bright and considerable runtime. 14500 and dummy for WOW FACTOR? …yeh, why not.
