This dimmable 50W LED magnetic strip retrofit kit replaces the ballast and tubes in 2' x 4' fluorescent troffers. Bright and powerful, the strips emit up to 6500 lumens in warm, cool, or natural white, equivalent to the output of three 32-watt fluorescent T8 tubes. Evenly-spaced magnets allow for easy and secure mounting. The constant-current driver allows brightness control with a 0-10V dimmer. Remove the existing ballast and direct wire the driver to your electrical system with the 18 AWG pigtail (driver input). This LED magnetic retrofit kit is perfect for homes, offices, schools, hospitals, and more!
