Correct, as one of their blogs shows the Amp draw difference from the P3X to the Charlie, Bravo and Malkoff model.
The Surefire’s were drawing more the the cells rated max Amps at first, although I believe that was to get 1,300 lumens out of the light turn on and still get 1,000 lumens out of the light at 30 seconds. To me, I do not like that. Yes, I own P2X Tactical, P3X Tactical Titan and Titan plus , PLUS all my Surefire WML’s.
Mean while I currently own ZERO Elzettas but will soon and I love their Constant output of at or above 900 lumens for about one whole hour.
Meanwhile, Surefire starts about 1,300 lumens and then decides to run a quick drop to about 650 lumens after just a few minutes. I will try to look up their graph
