WareLight's LED Linear Troffer and Industrial Strip Retrofit Kit Magnetic Strips are economic LED replacements for 2'x2', 1'x4' or 2'x4' existing fixtures in drop-in ceilings. They can also be used in existing industrial strips or wrap fixtures. The dimmable strips (arrays) come with a snap-in frosted lens to help reduce glare. The kits are magnetic backed for easy installation and include a quick-connect driver. The LED Retrofit Kit Strips replace traditional tubes in a variety of commercial applications, including offices, lobbies, hallways and conference rooms in schools, libraries, airports, showrooms and hospitality environments.
