Ryobi presents the 18-Volt ONE+ 20-Watt Dual Power LED Work Light. Never run out of power with the convenient option of using a ONE+ battery (sold separately) to operate the light, or switch over to electric power with an extension cord for prolonged use. In addition to the convenience of dual-power functionality, the work light produces over 1800 lumens to illuminate large work spaces and runs cooler than halogen or incandescent lights.
