Hey there folks - recently picked up a Surefire Fury single output flashlight for tactical use. Just wondered if you can get more than 500 lumens out of it if a rechargeable of some sort is used?
They market the K2 LFP chemistry 123As at 3.2v, so that is probably your best option, even though they're out of stock on them right now.
Convoy: S2, M1, M2, Fenix: P1D, PD32, HL30, Surefire: 6P LED, Zebralight: SC-600, Klarus: P2A, Jetbeam: BA-20, Icon: Rogue 1, L3: LD10, Xeno: E03, ShiningBeam: I-Mini, Olight: i3s, Sunwayman: D40A, M11R, V11R, Maglite: 6Ds w/TerraLux Ministar5s, Mini-Mags, Solitaires, LaCrosse BC-700, Maha C-9000, XTAR VP2, WP2 II.
the Fury uses a step down driver, therefore the higher voltage of rechargeables should not give You any increase in brightness. If You use 17670 or 16650 rechargeables, You will have something about 80% of the original output.
I use AW RCRs in mine all the time doesn't hurt it one bit, and it is just as bright as with SF primaries. Don't know about runtimes though.
I want a torch to see Heaven 'cause I have doubts that's where I 'm going.
