FEAT URE S ORDERING INFORMATION NOTES
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 emissions and provides higher heat tolerance and better protection than standard
borosilicate lenses.
• Center Beam optical system centers the lamp relative to the aperture, optimizing 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 adjustment assures complete coverage.
