Universal Retrofit System (URS)

This product is no longer available​

The Universal Retrofit System (URS) is the ultimate retrofit system for a variety of linear fluorescent light fixtures. Each URS is comprised of a patented aluminum extrusion, a high-efficacy set of LEDs, and an external dimmable driver. The URS is offered in two nominal lengths, 2′ & 4′, 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.

Applications: Automotive Lighting, Commercial Lighting, Food Processing Lighting, Industrial Lighting, Office Lighting, Parking Garage Lighting, Warehouse Lighting.
