Optics and Applications

This cylinder features use a two reflector system. The primary linear reflector is formed and faceted. The cross baffles are parabolic. The pattern is slightly asymmetric depending upon measurement parallel or perpendicular to the lamps. Use in corridors, transit areas, open spaces, foyers, restrooms, etc.

Design Features

Cross baffles are supported at the top for rigidity to insure the pre-set parabolic curve is maintained for predictable brightness control.

Finish

A specular clear Alzak cone is standard. Optional colors and Softglow® finishes are available. Interior finish is matte black, the cylindrical housing exterior is satin brushed, then painted matte white baked enamel.

Ballasts

Fully electronic, microprocessor controlled with variable starting current for inrush protection to assure rated lamp life. Input voltage range from 120V through 277V. Power factor .98, starting temperature 0°F (-18°C), THD < 10%. Pre-heat start < 1.0 second. End of lamp life protection. Rated for > 50,000 starts.

General

Fixtures are UL and C-UL listed for thermal and electrical safety. Union made IBEW. Luminaire Efficiency Rating (LER) data is in the photometric directory located in Section Z.
