EnviroLite LED troffers are the perfect solution for grid ceiling lighting needs. These light fixtures are designed to save energy and lower maintenance costs. The integrated LED light source uses 30% less power to produce the same amount of light as fluorescent ceiling lighting. The LED light source is built into the troffer; you don't have to replace bulbs ever. Because it's LED, you will never hear the hum that fluorescent fixtures make. This commercial lighting troffer provides cool white 4000K CCT light and is compatible with 0- to 10-Volt dimmers. The sturdy frame is easy to handle and installs directly into a grid ceiling using the built-in T-bar clips. The prismatic lens sits flush to the ceiling and distributes the light evenly. EnviroLite commercial lighting troffers are built to last for 50,000 hours and come with a 5-year warranty.
