Optics and Applications
A two reflector optical system maximizes the output of the vertically mounted Philips triple tube lamp. Small apertures do not perform properly with radically different lamp shapes. Philips is recommended for its photometric characteristics. The pattern is uniform with a soft edge to blend with adjacent units. Use anywhere as a general all purpose unit.
Design Features
The optical system has a multi-sectioned primary reflector and a parabolic low brightness shielding cone. A twist and lock socket prevents the lamp from falling if it is not properly engaged. It is a dependable fail-safe mechanism. Maximum ceiling thickness 1". Ballast and lamp service from below.
Finish
A specular clear Alzak cone is standard. Optional colors and Softglow® finishes are available. The housing and all structural parts are phosphated for corrosion resistance before being painted optical matte black for control of stray light leaks.
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 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.
