This PLT L624CL42U4K recessed troffer fixture is suitable for general or task lighting and installs beautifully as a recessed light. The L624C has a solid steel frame that's protected against rust and wear. The 3951-lumen LED light source is diffused by a translucent acrylic for even light distribution and less glare. The L624C is operated by regular 120 to 277-volt line voltage. This light is rated for 50,000 life hours of operation and will outlast any equivalent incandescent. The combination of a cool white, 4000K, color temperature and the recessed diffused lighting make this a great resource for office or home lighting.
