The design of Parabolic louvers represents the most sophisticated form of fluorescent lighting control in the lighting industry today. Optically perfect mirrored parabolic shapes are designed to reflect maximum light within 0..-45.. working zone and shield glare zone. The brightness control provides efficient illumination while eliminating the discomfort and eyestrain normally associated with source brightness and glare. Para-Lite 1 incorporates the typical design features creating the same low-key appearance often associated with incandescent downlighting. A soft understated visual image is produced by the small cell (1/2... x 1/2... x 7/16...) overall louver pattern. Regardless of source intensity or size, the Para-Lite 1 permits complete brightness control within normal viewing angles. Parabolic louvers shall be Para-Lite 1 as manufactured by Liteline Corporation, and shall be one piece injection moulded of (polystyrene or acrylic) with all parabolic surfaces prepared with primary undercoat, and a (highly specular) vacuum metalized finish or a (semi-specular/satin) painted finish. Cell dimensions shall be 1/2... x 1/2... x 7/16... and shall provide 44.. shielding with a louver efficiency of not less than 41%. This louver has a .99 VCP rating (specular silver finish). Available in nominal panel sizes of 2... x 4..., 2... x 2..., and 1... x 4....
