LED Universal Retrofit Light Bar


Universal Retrofit System (URS) is the ultimate retrofit system for a variety of linear fluorescent light fixtures. Each URS is comprised of a patent pending aluminum extrusion, a high-efficacy set of LEDs, and an external dimmable driver. The URS is offered in two nominal lengths, 2 and 4 ft, to retrofit the most popular installed housing. When the objective is to extend the useful life of installed fixtures while upgrading to LED with a robust, complete retrofit system with components that exceed those found in LED Tubes, Linmore’s URS is the clear choice.
