Featuring USB cord and adapters for connecting to cigarette plug receptacle/wall outlet, RL-15-LED-CPR is powered by 3.7 V Li-ion battery that offers 4.5 hr runtime. Five 3 W LEDs collectively generate 1,100 lm of cool white light while drawing 15 W, and LED assembly is protected by rustproof, die-cast aluminum housing and impact-resistant, polycarbonate lens. While articulated light head can be manually adjusted through 180° of vertical tilt, sealed power button on base simplifies operation.
