This dimmable LED magnetic strip retrofit kit is designed to replace the ballast and tubes in 2' x 2' fluorescent troffers. Bright and powerful—the 40-watt LED retrofit kit emits up to 5200 lumens of warm, natural, or cool white light—equivalent to the output of 4 17-watt fluorescent T8 tubes. They're designed to last 5 times longer than fluorescent lights. The LED lights have magnets every 5” for secure mounting, and they operate on 100-277 VAC. A 0-10V dimmable constant-current driver is included, and brightness can be controlled with a 0-10V dimmer. This LED magnetic retrofit kit is perfect for homes, offices, schools, hospitals, and more!
