Best Buy is pulling an move and completely ignoring the impossibility of the lumen rating, vs runtime too off AA cells.
Suppose for a moment that it was a top brand, even then, this form factor cannot support 1400 lumens, doesn't have the heatsink area to do that.
You'd have to be a masochist to put 6 x AA batteries in this and expect a good outcome, but if you have a stash of excess AA cells, as I do for emergency purposes because so many things can be powered by AA, it could still make sense to have this. Just don't expect 1400 lumens. It's probably closer to 600lm, which is still a fair amount of light, easily useful but the spec, meh.
The price is still reasonable but it's hit or miss, what better value you can find if you shop around. You're limited in options if you want something AA-powered with high lumens.
If you pulse these you can get as much as 1,000 Watts for a millionth of a second using PWM.
So, 100 lumen per watt = 100,000 lumens for 0.000001 or 10−6 of a second.
They use this marketing technique with amplifiers too.

Thank you!
