This versatile rechargeable flashlight is a useful companion in a wide range of everyday indoor and outdoor tasks. With a 21700 rechargeable battery and charging socket (USB-C) it offers four brightness levels (5/40/350/1200 lumens). It can also be powered by a 18650 rechargeable Li-ion battery or two CR123 batteries (max. 1000 lumens). A switch on the rear controls on/off and momentary light. Brightness levels and special modes (strobe and beacon) are activated by the switch on the side. A memory unit ensures that the EFC2r always turns on at the level you most recently used. A signal is given when the available battery capacity falls below 25%. A removable stainless steel clip is provided for convenience. The rugged aluminum housing is hard-anodized and waterproof as per IPX8. Comes with a nylon holster, lanyard, 21700 rechargeable Li-ion battery, charging cable, battery adapter and replacement seal.
