Specifications

Louver: PS = low iridescence specular pre-anodized aluminum (standard).

LS = low iridescence semi-specular pre-anodized aluminum. Note: both louver selections come with a virgin acrylic overlay to enclose all lamps. VA = .095" nominal thickness prismatic virgin acrylic.

Electrical: Instant start HPF, SB (Biax Type) thermally protected class "P" electronic ballast UL-listed. If K.O. is within 3" of ballast, use wire suitable for at least 90°.

Labels: I.B.E.W./UL and ULc Listed.

Performance: In an installation of 4 lamps 40 W luminaires in a room cavity of 1, with reflectance of 80% ceiling, 50% walls, 20% floor, the C.U. shall not be less than .61. To reduce glare the VCP shall be not less than 87 either length- wise or crosswise (at 100 fc level) and the average brightness at 65° shall not exceed 403 footlamberts. To prevent veiling reflections, luminaire output in the 30°-90° zone shall be not less than 59.0%.

Materials: Chassis parts are die-formed code gauge cold rolled steel. Housing has all edges turned over for safe handling.

Louver: Pre-anodized aluminum (Coilzak® or equal).

Overlay: Prismatic virgin acrylic, pattern 12.

Finish: Cavity—white baked polyester enamel minimum reflectance 86%. Phosphate undercoating. Chassis exterior—black baked polyester enamel to reduce ballast temperature.
