MS Series LED Retrofit Kit

The MS Series LED is a linear solution ideal for open-ceiling or suspended applications with mounting heights from 14 to 20 feet. Based on the time-tested MS housing, or retrofit kit for existing Lithonia Lighting MS8 or TMS8 housings, the traditional fixture offers design time-saving installation options making it a favorite for contractors. It can be installed in a continuous row or as a stand-alone unit. Its full-body construction and multiple mounting options adapt to a wide variety of suspended and open-ceiling applications.


The optical assembly is precision formed using 20-gauge steel and is provided with all hardware necessary to complete a retrofit. The lensing integrates seamlessly into the optical housing to provide a sealed chamber to mitigate dust and insect collection. Finish: High-gloss, baked white enamel finish. Five-stage iron phosphate pretreatment ensures superior paint adhesion and rust resistance.


Optical design distributes the light in the 0-60 deg. zone, which provides better utilization of light on task. Each linear bar is outfitted with premium, anodized MIRO 5® aluminum to ensure the highest lumens per watt can be achieved. A diffuse acrylic lens eliminates the pixels to minimize glare and improve uniformity.


The MSLR has 83% lumen maintenance at 60,000 hours with an expected life of greater than 100,000 hours. MSLR ships standard with a thermally protected dimming driver that dims to 57% using 0-10V controls. Please refer to for dimming solutions. You may also contact the Synergy Support at 800-533-2719 or LEDs are driven to provide optimal lumens per watt and less heat to extend component life. The driver and optical housing are connected with mating plug for easy removal or future upgrade.


MSLR is designed to retrofit the MS8 linear fluorescent fixture only. This kit ships with aircraft cable tethers to support itself during wiring. Detailed installation instructions are included with each luminaire.
