The MS Series LED is a linear solution ideal for open-ceiling or suspended applications with mounting heights from 14 to 20 feet. Available as a complete luminaire, based on the time-tested MS housing, the traditional fixture design offers time-saving installation options making it a favorite for contractors. It can be mounted 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.
Construction
The full-body housing and optical assembly is precision-formed using 20-gauge steel. The optical assembly ships factory-installed into the housing and utilizes aircraft cable tethers to support the optical assembly during wiring. The lensing integrates seamlessly into the optical housing to provide a sealed chamber to mitigate dust and insect collection. A convenient access plate is located on the back of the channel for access to the wiring compartment. Finish: High-gloss, baked white enamel finish. Five-stage iron phosphate pretreatment ensures superior paint adhesion and rust resistance.
Optics
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.
Electrical
The MSL luminaire has 83% lumen maintenance at 60,000 hours with an expected life of greater than 100,000 hours. The MSL ships standard with a thermally protected dimming driver that dims down to 5% using 0-10V controls. Please refer to http://www.synergylightingcontrols.com/ProductBrochures.aspx for dimming solutions. You may also contact the Synergy Support at 800-533-2719 or Support@SynergyLightingControls.com. 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. Optional 12AWG through-wire harnesses is available for continuous-row installations.
Installation
A variety of mounting arrangements are available including tong hangers, aircraft cables and stems. Suitable for mounting in continuous-row or individual mounting. End caps include knockouts for through wiring and fixture attachment in row-mounting applications.
