SPECIFICATION INFORMATION

Construction

The Curv Louvered series is constructed of heavy 20-gauge steel with a 2-3/4" x 9-1/2" profile. Fixtures are available with up to three lamps in cross section. Modular mounting points maintain convenient, predictable locations and fixture lengths in 48" increments. The exact shape of the housing is maintained by the use of an inner die cast plate at each fixture end throughout the row to provide row integrity. The housing is designed to wrap around the plate and secures on top with concealed screws to ensure housing tolerances are consistent. Standard light distribution is 60% uplight, 40% downlight; four additional options are available and are field retrofittable.

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.

Shielding

The luminaire comes standard with a low iridescence semi-specular louver (LD) to provide both direct and indirect illumination. If desired, a specular low iridescence (LS) louver may be specified. The parabolic louver snaps in from below for simplicity and ease of installation. The 17-cell louver measures 1-1/2" high and provides maximum efficiency to prevent glare.

Mounting

Curv Louvered is designed for ceiling suspension with an aircraft cable mechanism. To maintain consistent, predictable mounting points, 1- and 3-lamp fixtures use a yoke hanger and 2-lamp units use a single-point mounting system at each hanging location. Fixed cable has a total vertical adjustment of 1-1/4". The end of the 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 (standard) or optional coiled 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. Some ballast options are available as dual-voltage 120/277V. All fixtures are wired for single circuit operation. Additional circuits can be supplied as an option by designating IBOB or LR switching.
