SPECIFICATION INFORMATION

Construction

The Curv series is constructed of heavy 20-gauge perforated steel with a 9-1/2" x 2-1/2" profile. The perforations measure 0.0625" in diameter and provide a 23% opening per square inch and have a white acrylic diffuser overlay. Fixtures are available with two to four T8 lamps and one to three T5 lamps. A unique angling method on the center lamp of the three-lamp unit minimizes the length of the fixture without affecting the performance or operation of the unit. This lamp positioning ensures that all fixtures are made in four-foot increments. The exact shape of the housing is maintained by the use of an inner die cast plate at each fixture end. The housing is designed to wrap around the plate and secures on top with concealed screws to ensure housing tolerances are consistent. These die cast aluminum end caps and aligners provide zero tolerance alignment between fixtures, resulting in consistently straight rows with no snaking. The luminaire comes standard with a painted white steel reflector with specular inserts on the sides. A high efficiency reflector (HRF) option is constructed of high reflectance specular material and allows for wide distribution with maximum efficiency. An economical painted white reflector (WR) is available.

Finish

Housing and all painted parts are treated with a multi-stage phosphate prior to finish. Parts are then finished with a white RAL powder coat for maximum consistent coverage and longevity. Other colors may be specified.

Mounting

The Curv is designed for ceiling suspension and is provided with an aircraft cable suspension mechanism. The fixed cable has a total vertical adjustment of 1-1/4". End of cable barrel screws into a standard 1/4 20 bolt brought down from the ceiling. Cover plates are provided to shield the ceiling cutout. A straight or optional coil cord is available for feed locations. A feed canopy is provided for each feed location. All fixtures are suspended in modular increments and must be supported at each fixture-housing end.

Labels and Electrical

All fixtures bear appropriate UL labels. Fixtures are prewired with small case electronic ballasts and are available in 120V, 277V, or 347V. All fixtures are wired for single circuit operation, but additional circuits can be supplied as an option by designating IBOB or LR switching.
