Specifications

Specifications

Construction Formed highly reflective matte white pre-painted reflectors and ends are housed in rugged steel housing. Ends are both tabbed and screwed securely into each corner. Two KOs per end and large access plates in top of housing simplify wiring. Ends include integral grid locking feature and four auxiliary mounting points. Premium aluminum mounted LED boards are securely fastened to steel LED tray for superior heat dissipation and extended life. Drivers installed in separate compartment with room-side accessibility. Extruded acrylic enclosed lens has positive locking channel along the length of fixture. All exposed installed surfaces are matte white, pre-coated with a minimum reflectivity of 87%. All other metal surfaces are gloss white pre-coated.

Optical system Enclosed acrylic lens has advanced material formulation to produce even and high efficiency lighting. Reflectors light evenly and contribute to fixture’s efficiency and pleasing contrast. Fixture’s geometry prevents harsh cutoff and is designed for an even gradient of light on reflective surfaces.

Electrical All connections are made with high quality  quick connects. All supplied drivers are Class 2. 0-10 Volt (5% to 100%) dimming; power factor >0.9 at full load; operating temperature 14˚F (-10ºC) to 122˚F (50ºC). Safety standards: UL8750 / UL1310; total harmonic distortion: <18%; EMI: FCC Class B FCC Part 15; rated input voltage: 120V to 277V. Emergency lighting option ELS is available in all LED configurations to deliver 1000 lumens for 90 minutes minimum.

LEDS Aluminum core long life boards. LED chips available in 3500K, 4000K and 5000K. MacAdam binning is limited to 3 ellipses. >80 CRI for accurate color rendition. All LED options are LM80 tested. Life expectancy of 91,000 hours (L70).
