Product details:

1/150/500/1000/2000 Lumens, Cree XHP35 HI LED, 2000-Lumen Strobe, Dual Side & Tailcap Switches, Momentary and Constant-On Activation, Micro-USB Charging, Aluminum Housing, Type III Anodized, AR-Coated Glass Lens, Impact Resistant and Submersible. Combining the convenience of micro-USB recharging with a 2000-lumen maximum output the Acebeam L16 Rechargeable LED Flashlight is a versatile torch for law enforcement search and rescue military and similar applications. Dual push-button switches control operation of the light: one on the side for cycling through the settings and a tailcap switch for momentary activation and direct access to the turbo setting. Runtimes range from 500 hours on the one-lumen firefly setting to over an hour at peak output. The L16's 18650 li-ion battery recharges inside the light via micro-USB but the light can also run on two CR123A batteries if necessary. The aluminum housing is Type II anodized and IPX8-rated submersible to 6.6' and impact resistant to 3.9'. The glass lens of the light bears anti-reflective coating for maximum light transmission. Heat-sink construction helps dissipate energy from the hot LED.
