The MRI-TH recessed architectural LED luminaire is a non-ferrous lighting solution engineered specifically for magnetic resonance imaging (MRI) environments. Designed to deliver comfortable, low-glare general lighting, it combines visual performance with uncompromised MRI compatibility. Constructed entirely from non-magnetic materials and powered by a low-voltage DC system, this fixture ensures safe operation without interfering with sensitive diagnostic imaging equipment. With outputs up to 4000 lumens and full-range dimming down to 1%, it provides exceptional flexibility to support both patient comfort and clinical precision within healthcare facilities.
Engineered for demanding medical applications, the luminaire is available in 1x4, 2x2, and 2x4 configurations, making it adaptable to a variety of ceiling layouts. It meets specification-grade performance standards and is certified to CSA/UL requirements, ETL listed for insulated ceilings, and tested in accordance with IESNA LM-79. Suitable for damp locations, this fixture is ideal for hospitals, imaging suites, and other healthcare environments requiring non-magnetic construction.
The MRI-TH features a shallow, die-formed aluminum housing with a precision-formed internal reflector that ensures optimal light distribution. Its extruded acrylic diffuser delivers soft, low-glare, indirect light while maintaining high optical efficiency and wide uniform coverage. The fixture is finished with a five-stage pretreatment and antimicrobial matte white polyester powder coating, ensuring long-term durability and hygiene compliance in medical settings.
At its core, the high-efficiency LED light engine provides consistent performance and color stability. It is field-replaceable and serviceable from below, simplifying maintenance. Available in color temperatures from 2700K to 5000K, the luminaire maintains color uniformity within a 3-step MacAdam ellipse (SDCM) and offers standard 80+ or optional 90+ CRI for accurate color rendering. The LEDs are rated for a long lifetime, with an L70 value exceeding 60,000 hours, ensuring sustained performance and reduced maintenance intervals.
The electrical system operates on low-voltage (Class 2) DC power with constant current reduction dimming technology, supporting smooth, flicker-free dimming down to 1%. Power is supplied via scalable remote-mounted MRI power enclosures, maintaining a safe separation from the imaging zone to eliminate electromagnetic interference. Optional configurations include remote power and filter assemblies, allowing delivered lumen packages ranging from 1000 to 8000 lm to suit specific lighting design requirements.
Installation is streamlined for grid (T-Bar) ceiling applications. Mounting holes are provided for chain support to the building structure, along with integral earthquake clips for enhanced stability and compliance with seismic safety requirements.
Combining precision engineering, MRI-safe materials, and superior optical performance, the MRI-TH recessed architectural luminaire represents a reliable, specification-grade lighting solution for healthcare environments where electromagnetic neutrality, patient comfort, and visual quality are critical.
