Para-Lite 5
HIGH EFFICIENCY LOW BRIGHTNESS, SHALLOW DEPTH DESIGN

Specifications
Parabolic Louvers shall be Para-Lite 5 as manufactured by A.L.P. Lighting Components, Inc., and shall be one piece injection molded of polystyrene or acrylic with all parabolic surfaces prepared with a primary undercoat, highly specular vacuum metalized finish. Nominal cell dimensions shall be 3/4" x 3/4" x 3/8" high and shall provide 28 shielding with a louver efficiency of not less than 70%. This louver has a VCP index rating of .88 (specular silver finish) and a .75 coefficient of utilization for a RCR of 1.


Lighted Ceilings - Louver panels are designed to fit any standard 1' x 4', 2' x 2' or 2' x 4' tee bar grid system.

Special Sizes - Special sizes are available, contact A.L.P.

Flanged Style - Panels will sometimes require additional cutting for proper installation.

Lighting Fixtures - Louver panels can also be specified with the Avoida-Notch optional frame - to specify add suffix-AN50 to the base catalog number. For color designation use B for black, W for white. For specular finish color designation should follow SP (i.e., SPG for gold, SPS for silver).
