The Non-Ferrous MRI 6” LED Downlight is a precision-engineered luminaire specifically designed to meet the demanding requirements of magnetic resonance imaging (MRI) environments. As part of a complete MRI-compatible lighting system, it ensures absolute safety and operational reliability by employing non-magnetic construction and a low-voltage DC power system. This eliminates electromagnetic interference that could otherwise compromise diagnostic imaging accuracy. The fixture’s refined, low-profile trim departs from the overly clinical appearance typical of hospital luminaires, offering a more sophisticated aesthetic that contributes to patient comfort. Its sealed optical design and gasketed trim and reflector simplify maintenance while preventing dust accumulation, maintaining both hygiene and performance integrity over time. Delivering up to 3500 lumens with smooth, flicker-free dimming down to 1%, this downlight provides the flexibility needed to support both calming patient environments and functional clinical settings.
Built for healthcare and hospital applications, the MRID downlight combines technical precision with durable construction. Its housing is fabricated from 16-gauge aluminum and supported by vertically adjustable butterfly brackets for secure installation. Conduit or cables enter through ½-inch trade size knockouts, while the integrated plaster ring allows post-installation adjustments from below for ceilings up to 2.5 inches thick. The entire assembly, including heat sink, reflector, lens, and trim, is sealed using long-life EPDM closed-cell gasket materials to ensure superior air and dust protection. A die-cast, gasketed trim seals tightly to both the reflector and ceiling surface, maintaining a clean interface with smooth external surfaces that are easy to wipe down and disinfect—an essential feature in clinical environments.
The fixture’s optical assembly is factory-sealed to eliminate dust ingress, preserving optical clarity throughout its lifespan. A regressed, high-impact clear polycarbonate lens is permanently sealed into the reflector assembly, protecting the internal light engine while maintaining a refined visual appearance. The LED light source is a factory-sealed, COB-style (chip-on-board) engine designed for high efficiency, color accuracy, and longevity. It is field replaceable and serviceable from below the ceiling, ensuring future-proof maintenance access. Available in color temperatures of 2700K, 3000K, 3500K, 4000K, and 5000K, the MRID delivers exceptional color consistency within a tight 2-step MacAdam ellipse (2 SDCM). Users can select from 80+, 90+, or 97+ CRI options to achieve precise color rendering in clinical and patient-care applications. With a rated lifetime exceeding 80,000 hours (L70), the LED system provides long-term stability and reliability in demanding healthcare facilities.
Electrically, the MRID downlight operates on a low-voltage (Class 2) DC system utilizing constant current reduction dimming technology. It is compatible with scalable, remote-mounted MRI power enclosures such as the MRPE4, MRPE8, or MRPE12, which provide reliable and filtered power distribution. Optional MRI-grade RF filtering modules, including the MRFE4, MRFE8, or MRFE12, are available to further suppress electromagnetic interference across multiple zones or circuits, ensuring compatibility with sensitive MRI instrumentation.
Every detail of the fixture’s finish and installation system is tailored for medical-grade environments. The trim undergoes a rigorous five-stage pretreatment process before being coated in an antimicrobial matte white polyester powder finish, providing both durability and infection control. Installation versatility allows for recessed Type-IC configurations in T-bar grid or drywall (F-type) ceilings. The adjustable plaster ring accommodates ceiling thicknesses between ½ inch and 2.5 inches, and the fixture can be installed under a covered structural ceiling. To ensure MRI compatibility, wiring must be enclosed in a grounded metallic conduit system, and all mounting hardware—including brackets for lathers and C-channel installations—is designed for stability and alignment.
The MRID 6” LED Downlight is ETL listed to UL2108 and UL1598 standards for insulated ceilings and meets stringent healthcare codes with IP64 ingress protection and NSF certification for non-food zone applications. Its specification-grade construction, sealed optical design, non-magnetic materials, and full-range dimming capabilities make it an ideal choice for MRI suites and medical facilities that demand precision lighting without compromising diagnostic performance or patient comfort.
