FEAT URES ORDERING INFORMATION NOTES
OPTICAL SYSTEM
• Center Beam optical system centers the lamp relative to the true aperture,
optimizing lamp efficiency.
• Tool-less O°- 40° vertical and 355° horizontal lamp adjustments made with the
trim assembly removed for simple focusing. Lockable adjustment mechanisms
maintain focus during relamping and are visible from below the ceiling with trim
assembly removed.
• Self-flanged, semi-specular or matte-diffuse anodized cone designed to
minimize backflash. Contour cut reduces visibility of inner housing.
• Interchangeable upper reflectors provide narrow, medium and wide distributions.
These preset distribution patterns allow designers to achieve various design
objectives.
• 1/8” thick softening lens eliminates beam striations and ensures maximum
efficiency. Provides required protective shielding.
• Optical system retained by self-aligning torsion support springs.
• Internal housing components painted black.
MECHANICAL SYSTEM
• Black painted housing features tool-less top access and accommodates a
maximum 1-1/2” ceiling thickness.
• Tool-less re-lamp capability from above or below ceiling.
