Streamlight SL-20L Rechargeable Flashlight is a full-sized flashlight with the versatility and long-lasting power to illuminate any situation. Built with a case made out ofimage machined, aircraft grade aluminum and a 50,000 hour, shock-proof C4 LED bulb, these Streamlight flashlights mean business and are built to last. They're bright, too, capable of pumping out 350 lumens on their highest setting and lasting for up to 50 hours on their lowest. Three different lighting modes - Low, Medium, and High - allow you to choose the appropriate lighting for the job with a multi-function, push-button barrel switch that can be operated with one hand. The Stream Light SL20L Full-Size C4 LED Flash Light is completely rechargeable, with an illuminated switch housing that displays the flashlight's charge status and a fast recharge time of 7 hours. Streamlight has equipped the SL-20L with a deep-dish parabolic reflector that provides a tight, focused beam with enough peripheral illumination to give context. These LED flashlights meet standards for IPX4 water resistance and have been tested for impact resistance up to 1 meter. For variable intensity lighting in a durable case that can be conveniently recharged at any time, choose the Stream-Light SL 20L Rechargeable IPX4 Light.
