Twice the lumens of a Fenix TK20R - a whopping 2000 lumens USB rechargeable LED flashlight.

The Acebeam L16 is a micro-USB rechargeable flashlight dedicated to law enforcement, search and rescue, military and similar applications. The brightest tactical flashlight in our range utilizes a CREE XHP35 HI LED with a max output of 2000 lumens and a beam of 603 meters. The L16 is a high-performance flashlight innovatively equipped with two independent light switches: a side switch provides access to five modes and a strobe while the tail switch allows one-touch access to turbo mode and tactical momentary illumination. The light is powered by an Acebeam IMR18650 rechargeable Li-Ion battery (included) but is also compatible with 2 x CR123A disposable batteries. The Li-Ion may be charged externally, or rapid-charged inside the L16 by connecting the built-in micro-USB port to any USB power supply. A selection of filters and a remote switch for weapons mounting - indispensable for hunting and tactical use - are available for this flashlight.
