Ends at 9PM PT. MidnightBox.com has the 5W CREE T6 1000LM 1 LED Flashlight Torch for $8 + $4 shipping = $12 shipped. Designed with waterproof aluminum alloy body and high/low/SOS modes.
The description says 5w, 1000 lumen. However, the Cree T6 is far less efficient than 200 lumens/watt. Therefore, the description is bogus.
Even worse, if you look at 'deal 4' they say it is a 6 led 1200 lumen headlamp for only $2.49. It doesn't mention cree at all. I suspect the headlamp may be able to put out 120 lumens on a good day.
Most likely around 170 lumens on a fresh battery before extended running heat and optics inefficiencies are factored in, resulting in closer to 150 lumens out the front for the first few minutes of operation.
It's worth a bit more having the T6 LED (if that's true), and underdriving it from a AA cell it'll be more efficient than some, but a AA cell can't produce the current needed for remotely close to 1000lm for more than the first second or two after it is turned on.
200 lumens is possible but not likely if it can run for over 20 minutes, then either/or it would have the battery at lower voltage and lower light output, or be so dim you found it barely usable.
That's beside the point though... power LEDs with a good heatsink and power source can run at high current but you won't find these factors in any compact 1 x AA cell powered light no matter the price. Instead they opt for a far more reasonable current under 700mA and under 200 lumens. If you want more, pick a different form factor that's larger and uses 2 x AA or > volume than a 14500 Li-Ion cell.
wow, what a bargain. normally on sale for $5, now $12...

..... I own one of these flashlights and you are correct.....200 lumen at best.
Who ever bought this led flash light bought a 100lm or less using a AA battery.
T6 750 ma = 280LM 1000ma = 388lm
Use a 1000ma rechargeable battery and the user of this flash light and achieve 300lm. The flash should operate for at least 40 minutes on one charge.
