BSS120
light distribution

Features

The BSS120 is a shallow profile LED luminaire for cove applications requiring quality asymmetric light distribution. The heavy gauge, sheet formed housing is fitted with a primary and saw-tooth reflector to produce a smooth, uniform gradient light across the ceiling plane. A clear dust cover shields the reflector system and 90+ CRI LED modules.

The BSS120A is designed to integrate with a manufactured cove system (consult factory for compatibility details).
