Product Description

High- and Low-Bay HID Fixtures Fixtures are sold as ballast housings or complete units. Ballast housings are die-cast aluminum with baked, white polyester, powder-coated finish




For high mounting heights that require high efficiencies, horizontal illumination and premium contrast control. Optimum performance for high ambient temperatures and harsh environments. Ideal for heavy manufacturing areas, warehouses, retail aisles and gymnasiums.


Construction

Housing: Rugged, heavy-duty, die-cast aluminum with white polyester powder finish. Electrical components horizontally opposed and heat-sinked to ballast housing.

Optics

Self-cleaning, ventilated design carries optical contaminants out through top of reflector. High-efficiency, high-performance, heat-resistant borosilicate glass reflector mounted within heavy-gauge rigid wire form rings and rods fitted to top and bottom of reflector. Yields high vertical footcandles with low brightness and excellent contrast control.

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: Glazed porcelain, vertically oriented, mogul base socket with copper alloy, nickel-plated screw shell and center contact.

Installation

Cast-aluminum pendant splice box threaded for 3/4" conduit (standard). Other mounting options available.
