The Nextorch C4 is an LED flashlight with a maximum output of about 700 lumens, powered by a single 18650 lithium-ion battery. The 18650 cell gives a good balance of size and runtime and can be recharged many times, so it suits everyday carry, security work, camping and the car. The light is rated IPX7, which means it is waterproof against heavy rain and brief immersion. Nextorch is known for tough, practical lights used by police, security and outdoor users.
