OPTICAL SYSTEM
•
Three preset distribution patterns allow designers to achieve various design
objectives. Clear anodized upper reflector and 6-inch self-flanged semi-specular,
matte-diffuse or specular finishing trim provide 50° cut-off, optimal efficiency
and glare control while maintaining a smooth beam pattern that is free of hot
spots and striations.
•
Compound contour finishing trim optimizes efficiency, improves beam symmetry
and visual comfort, regardless of vertical position.
•
Protective lamp guard utilizes clear ceramic technology that reduces UV emis-
sions and provides higher heat tolerance and better protection than standard
borosilicate lenses.
•
Center Beam optical system centers the lamp relative to the aperture, optimiz-
ing luminaire efficiency.
MECHANICAL SYSTEM
•
One-piece die-cast aluminum housing provides 3 square feet of surface area to
dissipate heat. Entire housing is coated with black paint to minimize visibility
when installed in open ceiling construction.
•
Tool-less, lockable 0° – 30° continuous vertical aiming appropriate for sloped
ceilings or applications requiring projection of the beam beyond nadir. Not
recommended for straight downlight applications. Full 360° horizontal adjust-
ment assures complete coverage.

ment are shipped pre-installed. Post installation adjustment possible without
the use of tools from above or below ceiling.
•
