The surface-mount ceiling light, available in 12"×24" and 12"×48" configurations, is engineered for secure, demanding environments where durability, safety, and reliability are essential. Designed specifically for institutional and correctional applications, this luminaire combines a reinforced structure with a clean, architectural appearance. Its one-piece die-formed housing is TIG-welded for exceptional strength, ensuring seamless corners with no post grinding for a smooth, uniform finish. The robust construction resists tampering, impact, and contraband concealment, making it ideal for use in behavioral health centers, correctional facilities, and other secure indoor spaces.
The luminaire’s lens system is retained by vertically adjustable, continuous “Z” brackets made from prime-grade material, secured to the housing with thru-studs spaced no more than six inches apart. This design provides continuous pressure along the lens edge, ensuring a tight, secure fit that prevents removal or prying while maintaining visual consistency. Lens options range in thickness from 0.125" to 0.625" and include a variety of prismatic, textured, clear polycarbonate, and tempered glass configurations. For optimal light diffusion and strength, a prismatic inner lens paired with a clear outer lens is recommended, though two clear lenses cannot be combined.
The fixture’s door assembly is a single die-formed piece constructed from prime-grade material, TIG-welded for added rigidity and alignment precision. It includes a staked and welded external piano hinge with a ½-inch knuckle and ⅛-inch pin for reliable operation. Optional internal and full-length internal hinges are available for additional security and aesthetic preferences. Hardened, tamper-resistant security fasteners secure the housing and lens assembly, ensuring long-term stability and preventing unauthorized access.
Electrically, the luminaire operates on 120–277VAC or 347VAC at 50/60Hz and features a serviceable, high–power factor constant-current LED driver with less than 20% total harmonic distortion (THD) and greater than 0.95 power factor (PF). The system supports standard 0–10V dimming within a 1–100% range and offers dim-to-dark capability for all voltages except 347V configurations. A maximum source current of 330 microamps ensures efficient, low-noise operation. Color temperature options include 3000K, 3500K, 4000K, and 5000K, with a minimum 82 CRI for balanced, natural light output suitable for visually demanding environments.
The housing is finished with a TGIC polyester powder coat applied after a five-stage pre-treatment process to enhance corrosion resistance and finish longevity. The coating achieves a 92% reflectance and withstands 1,000 hours of salt spray testing, ensuring long-term aesthetic and structural performance in challenging environments.
This ceiling light is designed for surface mounting using secure external mounting hardware and is fully recessed where required. Its robust design makes it ideal for use in correctional cells, dayrooms, corridors, sally ports, locker rooms, showers, cafeterias, containment areas, and other behavioral or institutional settings. Certified to UL and CUL standards for damp locations, the fixture can also be configured for wet-location use depending on project requirements.
By combining tamper-resistant engineering, serviceable LED components, and a precision-welded housing, this luminaire delivers unmatched reliability and safety in environments that demand secure and maintenance-friendly lighting solutions.
