*Runtime (14500): High output at 1A: 450 lumen max for 56 minutes. Although it’s a nice enough light, I won’t buy a light when they fudge the numbers. I just don’t like deceptive marketing. I agree with kreisler.
206 lumens isn't much of a barn burner for $39. I would trust Crelant's rated 450 lumens to be in the ballpark from prior BLF Crelant reviews. Plus the 4Sevens Quark AA2 is 2 AA's, while the Crelant is 1 AA or14500 light. For the AA2 at 6.2 inches, I would go with a 18650 light instead. The AA2 has a whole bunch of advanced features (selectable modes including moonlight), and maybe it throws good, but for sheer output, it can't compare.
Ahh, interesting... I was looking at the XP-G R5 version, not XML -- the XP-G R5 is different all-around (size, reflector, etc.). The XML version is rated at 280 lumens, but SELFBUILT measured it at 420 running 2 NiMH Eneloops in it -- not bad, but still at 5.8 inches, it's up there in length. I would prefer the V31A - for some reason the dimensions of width is equal between the V11A (AA) and V31A (CR123A).
I wouldn't write off the V11A so quickly, before anyone thoroughly reviews it. Mark at MD-LightSource only carries quality lights, he's an active Police Officer, and carries the full line of Crelants. If you saw his posting, the weekend he got in his first shipment of the Crelant new designed lights, he basically was sold out. I'm not sure why the reviews aren't showing up yet though if so many were sold day 1 .
