The NAPA 85-911 work light's 2200mAh rechargeable lithium ion battery provides plenty of the power and operating time. The lithium ion battery provides longer life, no memory effect and a much slower discharge than traditional Ni-MH batteries. Use the powerful 3 Watt directional torch, or the ten super-bright SMD LEDs, which provide up to 400 lumens output, to illuminate the entire work area. The unique 360 swivel and tilt function lets you position the light source in virtually any direction, while three magnets and two swivel hooks allow hands-free operation. This work light is a must-have!
