The 2'×2' patient room LED troffer light is a versatile ceiling-mounted luminaire that combines functional ambient and reading light in one low-profile fixture, supporting the comfort and clinical needs of modern healthcare environments. Available for surface, grid, or flange mounting configurations, this troffer is ideal for patient rooms and isolation areas, where both visibility and hygiene are critical. An optional Ingress Barrier Door ensures a sealed, smooth surface for easy cleanability and infection control compliance, maintaining consistent protection across the fixture’s visible surface.
Constructed from heavy-duty extruded aluminum with a clear satin anodized finish, the doorframe is available in two configurations: IB-AC or IB-HD. The IB-AC version is supported to the housing with aircraft cables, achieving NSF2 certification, while the IB-HD option incorporates a continuous hinged doorframe for seamless accessibility. Stainless steel Phillips-head fasteners secure the doorframe to the housing, while a closed-cell neoprene/EPDM/SBR gasket ensures a reliable seal between the frame and the fixture body.
The luminaire’s electrical system supports color temperature options of 3000K, 3500K, 4000K, and 5000K with a minimum 82 CRI for accurate color rendering. It accepts 120–277VAC, 50/60Hz or 347VAC, 60Hz input power and operates through a serviceable, high power factor, constant-current electronic driver with less than 20% total harmonic distortion and greater than 0.95 power factor. Standard 0–10V dimming enables smooth adjustment from 1–100% brightness, with dim-to-dark capabilities on most voltage configurations. An optional LVCD low-voltage control interface allows patients or staff to independently manage ambient, reading, and exam modes with dimming functionality.
The housing construction varies by mounting type for optimal strength and performance. Flange and grid models utilize 20-gauge cold-rolled steel in a seamless one-piece design, while surface-mounted versions use 18-gauge cold-rolled steel with full seam welding. All housings are finished in a white TGIC polyester powder coat with a five-stage pre-treatment for corrosion resistance and undergo a 1,000-hour salt spray test. The high reflectance (92%) interior enhances visual comfort and efficiency, while non-IB flange interiors are treated with a matte black TGIC powder coat to minimize glare.
Installation flexibility is built into every model. Surface-mounted versions use four 0.312-inch mounting holes for secure ceiling attachment. Grid-mounted fixtures accommodate standard 1-inch grids, with integrated hanging brackets for connection to the building structure. Flange-mounted fixtures come equipped with yoke brackets and installation frames that ensure precise alignment within ceiling openings—eliminating the need for drywall backing by incorporating its own structural support.
Lamp shielding is carefully configured for each compartment of the luminaire. The exam section of the 2'×4' configuration includes a sliding semi-specular aluminum parabolic louver with a clear protective lamp shield mounted above it. Ambient lighting is diffused through a perforated steel panel, finished in white TGIC polyester with a pearlescent acrylic overlay for uniform distribution. The reading compartment uses a clear protective lamp shield for visual clarity. When the Ingress Barrier option is specified, clear lamp shields for the exam and reading areas are omitted, as the sealed doorframe fulfills the protective role.
The fixture is UL and CUL Listed for Damp Location applications, with Ingress Barrier models achieving UL Certified IP65 per IEC 60598 and NSF2 Splash Zone compliance (IB-AC only). Its low-voltage controller option is protected under U.S. Patent No. D562,767, highlighting a unique patient-friendly lighting control system for healthcare environments. This robust combination of cleanability, performance, and flexibility makes the LED troffer a dependable choice for patient rooms, isolation areas, and other clinical settings that require consistent, hygienic, and adaptable lighting.
