EnviroLite LED troffers are the perfect solution for grid ceiling lighting needs. These commercial light fixtures are designed to save energy and lower maintenance costs. The integrated LED light source inside uses 30% less power to produce the same amount of light as fluorescent ceiling fixtures. The LED light source is built into the troffer so you don't have to replace Lamps ever. Because it's LED, you will never hear the hum that fluorescent light fixtures make. This commercial lighting troffer uses only 35-Watt to provide 3000 Lumens of cool white 4000K CCT light. The sturdy frame is easy to handle and installs directly into a grid ceiling using the built-in T-bar clips. The white lens sits flush to the ceiling and distributes the light evenly; you won't see dark spots or tube lines. EnviroLite commercial lighting troffers are built to last for 50,000 hours and come with a 5-year warranty. They are UL listed and IC rated for contact with insulation and can be installed in damp locations. They accept 120/277-Volt input and are fully dimmable using a 0-10-Volt dimmer. These troffers are DLC listed to qualify for commercial lighting rebates and special incentives in certain areas.
