Optics and Applications
The primary reflectors maximize the output of two energy efficient quad tube lamps. The parabolic shielding cones offer low brightness visual comfort from all normal viewing angles. Use in entries, corridors, transient spaces, and for task lighting in low to medium height ceilings.
Design Features
Construction allows easy access to all components. Efficient air flow design and extensive heat testing assure cool fixture temperature for optimal lamp performance. Steel housings protect the reflectors and assure their proper relationship for maximum performance. Maximum ceiling thickness 2". Ballast and lamp service from below.
Finish
Specular clear Alzak cones are standard. Optional colors and Softglow® finishes are available. Housings and structural parts are painted optical matte black to suppress stray light leaks. Steel parts are phosphate conditioned for corrosion resistance before painting.
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), HD < 10%. Pre-heat start < 1.0 second. End of lamp life protection. Rated for > 50,000 starts.
General
Fixtures are pre-wired, UL and C-UL listed for eight wire 75°C branch circuit wiring. Union made IBEW. Luminaire Efficiency Rating (LER) data is in the photometric directory located in Section Z.
