Despite its decidedly small footprint, this rechargeable flashlight is capable of generating a truly incredible beam of light. Its amazing feature, in fact, is the Turbo mode, which allows for maximum light output in an instant. The #3933 has a basic output of 2500 lumens that becomes 5000 lumens with Turbo mode, but it also has a simpler zoom mode.Features:Rechargeable Flashlight With 2500 Lumens OfPower And 5000 Lumens In Turbo ModeIn MetalWorks With A Rechargeable 20650 Battery (Included)4 Modes:100%: Power Off After 2hrs40%: Turn Off After 8hrs5%: Power Off After 10hrsTurbo: Power Off After 10sZoom FunctionWaterproofUsb Cable IncludedCharging Time: 5hrsWeight 300gr
