The linear surface mount ceiling light, available in 12"×24" and 12"×48" configurations, is a robust and secure fixture designed for demanding institutional environments such as correctional and behavioral health facilities. Engineered for strength and reliability, its one-piece, TIG-welded housing features continuously seam-welded corners that are smoothed without post grinding to create a seamless, tamper-resistant structure. The clamshell housing design enhances resistance to penetration and contraband concealment, ensuring lasting durability and security. The fixture incorporates a full-length concealed internal piano hinge with a heavy-gauge construction, complete with a secured pin and welded housing connection for added integrity.
Constructed from prime-grade materials, the baseplate includes a die-formed blade trap with a minimum ¼" depth to eliminate contraband concealment points and prevent unauthorized access. Embossed standoffs within the baseplate maintain rigidity and prevent distortion during installation or maintenance. The fixture’s vertically adjustable Z-bracket lens retention system uses thru-studs spaced no more than six inches apart, ensuring a secure and even fit across the lens assembly.
The luminaire is available with a wide selection of lens types, including prismatic acrylic, textured and clear polycarbonate, and tempered glass, in various thicknesses up to 0.875". A prismatic inner lens paired with a clear outer lens is recommended for optimal visual comfort and uniform light distribution; however, dual clear lenses cannot be specified together. The lens retention system is fully integrated into the housing design, providing secure containment and reliable performance even in high-abuse environments.
Internally, the fixture utilizes high-quality LED lamp sources with color temperature options of 3000K, 3500K, 4000K, and 5000K, all featuring a minimum color rendering index (CRI) of 82. The LEDs are powered by a serviceable high power factor electronic constant-current driver with less than 20% total harmonic distortion and greater than 0.95 power factor. Standard 0–10V dimming allows for a full 1–100% dimming range with dim-to-dark capabilities, except for 347V models which provide non-dim-to-dark operation. The driver operates at 120–277VAC or 347VAC, 50/60Hz input and features a maximum source current of 330 µA, ensuring consistent, efficient operation.
The fixture is finished with a TGIC polyester powder coat applied over a five-stage pre-treatment process, providing superior corrosion resistance and long-term color retention. This finish achieves a 1,000-hour salt spray rating and a 92% reflectance value, ensuring optimal light performance and surface durability. All hardware, including fasteners, consists of hardened security screws that are fully recessed to prevent tampering and maintain a smooth exterior profile.
Installation of the linear surface mount ceiling light is intended for secure, permanent applications and is not suitable for surface conduit or continuous row mounting. The fixture is certified to UL and CUL standards for damp locations and is compliant with the Build America, Buy America Act. Combining durability, security, and visual comfort, this fixture is ideal for cells, dayrooms, restrooms, corridors, cafeterias, locker rooms, sally ports, and other correctional or institutional indoor environments where safety, reliability, and tamper resistance are essential.
