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.

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.
