The recessed ceiling light, measuring 12"×12", is a robust and secure lighting solution designed for correctional, behavioral health, and institutional applications. Its construction emphasizes strength, durability, and safety, featuring a TIG-welded housing with no post-grinding required, ensuring maximum structural integrity. The light incorporates a vertically adjustable bracket secured to the housing via thru-studs, along with a completely concealed internal drop slot piano hinge, providing a clean, seamless appearance while maintaining functional accessibility. Ligature-resistant construction further enhances safety, making the luminaire suitable for environments where tamper resistance is critical.
Applications for this recessed ceiling light include cells, dayrooms, cafeterias, washrooms, showers, corridors, and sally ports. The fixture supports a wide range of lens options to meet specific design and functional needs. These include prismatic acrylic and polycarbonate lenses, textured polycarbonate, clear polycarbonate, clear tempered glass, and diffused acrylic variants, with thicknesses ranging from .125" to .500". The recommended configuration pairs a prismatic inner lens with a clear outer lens, while using two clear lenses in combination is not permitted.
The door of the luminaire is constructed from one-piece die-formed prime grade material, with continuously seam-welded corners finished smoothly without post grinding. Electrical options include 3500K, 4000K, and 5000K color temperatures with an 82 CRI, supported by a high power factor electronic constant-current driver operating at 120–277VAC and 50/60Hz, with a total harmonic distortion of less than 20% and a power factor greater than 0.95. Standard 0–10V dimming allows control within a 10–100% range, and the driver provides a maximum source of 500 μA. Fasteners are hardened security screws that are fully recessed, further ensuring the fixture's tamper-resistant qualities.
The housing is constructed from die-formed prime grade material with lapped and spot-welded assembly, providing a strong and reliable structure. A TGIC polyester powder coat with a five-stage pre-treatment delivers a durable finish, tested to withstand 1,000 hours of salt spray and offering 92% reflectance. The concealed spring-loaded internal drop slot piano hinge, secured with a pin and knuckle system, mounts to either side of the housing through keyholes, enhancing both durability and visual cleanliness.
Lens retention is achieved through vertically adjustable continuous “Z” brackets made of prime grade material and secured via thru-studs spaced up to six inches apart. The fixture is UL and CUL listed for damp locations, with additional options for wet location applications. It is not IC-rated and is compliant with ligature-resistant standards as well as the Build America, Buy America Act. A polyurethane luminous seal prevents light leaks from the base of the luminaire, ensuring both performance and aesthetic integrity.
Overall, this 12"×12" recessed ceiling light combines secure, ligature-resistant design with precision construction, versatile lens options, and reliable electrical performance, making it an ideal choice for correctional, behavioral health, and institutional settings.
