Narrow Industrial Enclosure

Ideal for use in cold, wet or damp environments where an attractive yet shallow enclosure is required - such as parking garages, industrial facilities, retail malls and multi-purpose centers. Well-suited for lower mounting heights where wide fixture spacings are required. Certain airborne contaminants can diminish integrity of acrylic. Refer to Acrylic Environmental Compatibility tables for suitable uses.


Shallow 4" depth overall and attractively contoured diffuser 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.

Power connection is easily accommodated through pre-drilled holes at each end, with wet location fittings provided for maximum flexibility. 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.


All standard ballasts are electronic, energy saving, thermally protected, Class-P, HPF, non-PCB, Sound Rated A, UL/CSA certified where applicable and comply with 4 Federal Ballast Law (Public Law 100-357, 1988). Default ballast configuration is for two-lamp ballasts except for one-lamp fixtures.

UL listed wire, rated for required temperatures, used throughout.


May be surface mounted or suspended by chain or cable. Stainless steel mounting brackets included (two per luminaire), pre-punched for easy field-attachment of bolts, screws and other mounting hardware.
