The Maglite ML150LR Rechargeable LED Flashlight will recharge to 80 percent in a half hour with a full charge at 2.5 hours. It's got 1082 lumens and it will run at that level for more than 3 hours, unlike other flashlights that boast high lumens, but will barely last! In eco-mode, the ML150LR will go for 79 hours nonstop with usable light. The beam throw is rated at 500 yards! You can thank Maglite's patented LED Heat-Sink Technology for that kind of all-star performance. All that power and it still weighs under 1 pound.
