An attractive and energy-efficient surface-mounted or suspended linear `fluorescent luminaire, suitable for wet, damp and/or cold locations. For challenging situations where relatively low fixture mounting heights and wide fixture spacings are common — such as parking garages, industrial facilities, retail malls, multi-purpose centers and airports.Certain airborne contaminants can diminish integrity of acrylic. Refer to Acrylic Environmental Compatibility table for suitable uses.


Shallow 4" depth overall and attractively contoured di? user obscure lamp while maintaining high transmission of light. One-piece fiberglass housing with integral perimeter channel utilizing continuous poured-in-place closed cell gasket. Tool-less ballast and wiring access. Stainless steel latches are standard.

Easily mounted to ceilings and structure, or suspended with chain, cable or rod, using mounting brackets (included).


Precision-formed, high-performance, 95% total reflectance optics utilizing premium specular aluminum warranted for 25 years. White ballast cover has 93+% total reflectance and is finished with an in-house polyester powder coating system.

Factory-installed lamps are available in various CRI ratings, temperature colors and rated life. Lamps are secured with rotary locking lamp sockets for ease of relamping and to reduce lamps disconnecting due to vibration or incidental contact.
