Features
The BSS121 is a shallow profile LED luminaire for cove applications requiring quality asymmetric light distribution and high lumen levels. 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.
