Acrylic Optical

by Lithonia Lighting

For high mounting heights that require higher efficiencies, general horizontal/high vertical illumination and premium contrast control. Ideal for light manufacturing areas, warehouses and retail aisles. Certain airborne contaminants can diminish integrity of acrylic. Refer to Acrylic Environmental Compatibility tables for suitable uses.


Construction

Housing: Heavy-duty, die-cast aluminum halves. Ballast and electrical components are heat-sinked and horizontally opposed for cooler operation. Integral splice box mounting flange ensures structural integrity. Electrostatically applied white polyester powder paint.

Optics

UV stabilized, high efficiency, high performance acrylic reflector yields high vertical footcandles while maintaining low brightness. Optical assembly is fully adjustable and accommodates a range of light distributions. Self-cleaning, ventilated design carries contaminants out top of reflector. Coated lamps provide optimum performance.

20% uplight.

Electrical

Ballast: All ballasts are 100% factory tested. HPS: Constant wattage autotransformer. MH: 175-450W fixtures shipped within the U.S. require super CWA pulse start ballasts which are 88% efficient and EISA-legislation compliant (must specify SCWA option). CSA, NOM or INTL options required for probe start shipments outside the U.S. 1000W is constant wattage autotransformer.

Socket: Vertically oriented mogul base protected exclusionary "PINK" socket with copper alloy, nickel-plated screw shell and center contact. For use with O-rated, protected metal halide lamps only.

Installation

Pendant splice box threaded for 3/4" conduit (standard). Pendant splice box – removable cast-aluminum box slides on integral die-cast aluminum housing mounting flange and mounts to 3/4" pendant conduit prior to ballast housing installation. Matching wire access cover accepts RELOC® modular wiring. Complete assembly meets or exceeds UL 50-pound pull test. Other mounting options available.

Optical mounting: Adjustable reflector mounting brackets are progressively die-formed of 18-gauge galvanized steel. For areas where reflectors are subject to impact (gymnasiums, etc.) To protect reflector from breakage; use full wire guard (FWG) option for areas where reflectors are susceptible to impact.
