Prewiring: 3/8” factory prewired cable (three no. 18 AWG leads, 6’ long),

Suffix: FF6, (Four no. 18 AWG leads, 6’ long), Suffix: FF14.

Fusing: Internal fast-blow fusing. Suffix: GLR. Internal slow-blow fusing. Suffix: GMF.

Fluorescent Emergency Lighting System: Factory-installed emergency power battery pack with charger and inverter, concealed in fixture channel. Operates one fluorescent lamp at reduced light output for 90 minutes. Suffix: EM.

Radio Interference Filter: 120 or 277 volt, 50 or 60 Hz.

One per fixture. Suffix: R. One per ballast. Suffix: B.

Electrical Options: Special wiring, fusing or dimming ballasts and installed lamps are available, consult your Lightolier representative or factory.

T-Bar Spacer: If T-bar is less than 1-1/2” deep, order Catalog Number: STC. 2 each end is required.

Specifications

Performance: In an installation of 2 lamp 31W Iuminaires in a room cavity ratio of 1, with reflectance of 80% ceiling, 50% wall, 20% floor, the C.U shall not be less than 64. To prevent glare the VCP shall not be less than 88 either lengthwise or crosswise (at 100fc level) and the average brightness at 65° shall not exceed 206 foot-Iamberts. To control veiling reflections, luminaire output in the 3C°-90° zone shall not be less than 68.6%.

Specifications (continued)

Air Return: Designed to provide optimum air return. Air is returned through the lamp compartment for all ceiling systems and direct to plenum through slots in slot grid and narrow grid ceiling systems.

Materials: Chassis parts are die-formed code gauge cold rolled steel. Housing is embossed for rigidity with all edges turned up for safe handling. Louver is pre-anodized aluminum (Coilzak® or equal).

Finish: Louver–semi-specular anodized low iridescence, vertical grain reflector sheet. Cavity–white baked polyester minimum 86% reflectance. Phosphate undercoating. Chassis exterior–black baked polyester enamel.

Electrical: Thermally protected class “P” ballast C.B.M. approved, non PCB. If K.O. is within 3” of ballast, use wire suitable for at least 90°.

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