For less than half that price, a similar "1000 lumen" flashlight can be had at Home Depot through this holiday season. The Husky light is powered by AAA batteries though (which is a plus for me...I don't like rechargeable)
Just more options for GJ members before they pull the trigger:

You're comparing apples and orangatans. That husky light is a toy. It doesn't make anywhere close to 1,000 lumens, and certainly not for the 1.5 hours advertised. It simply can't running on 4 alkaline AAAs, even if it had a highly efficient LED and driver (which it doesn't).
In order to get close to the max efficiency for a common led, you would have to run those AAA's in a 2S2P configuration, which means 3 volts at a max of 2.5 amp hours. That's 7.5 watt hours of total energy. But the max discharge current of an alkaline AAA is about 500 mA (double that for 2 in parallel) so 1 amp max. That means max power of about 1 amp to the LED at a full charge voltage of 3 volts so about 3 watts. The most efficient leds available are about 250 lumens per watt, so assuming a very efficient LED and a driver pushing those batteries to their absolute max, you'll get 750 lumens (before factoring in all the practical efficiency losses).
The lumintop comes with a 5 Amp hour 21700 Li Ion (4.2 volts) . That's a theoretical max of 21 watt hours of energy but what's more, it's rated for a 20 Amp discharge rate. 20 Amps at 4.2 volts is over 80 watts (compared to 3 above). But this light could make the claimed 1,000 lumen theoretical max output (assuming the same LED) with just 4 watts of power, or about 1 amp of current (remember it's capable of 20 amps.) in other words, it can easily make 1,000 lumens, at least until it gets hot, but that's an issue with any light this size.
You may not like rechargeable batteries, but there's no denying what they're capable of.
