The 6" patient room LED downlight combines refined aesthetics with exceptional functionality, creating a lighting solution ideal for healthcare environments such as hospitals, nursing homes, and patient rooms. Its low-profile trim introduces an understated elegance that avoids the sterile, institutional appearance common to medical-grade fixtures. Designed as a gasketed, regressed lensed luminaire, it forms a complete seal at the ceiling plane to prevent contaminated air from entering the patient space. Delivering up to 5000 lumens with smooth dimming down to 1%, this fixture provides the flexibility and comfort required by both patients and medical staff.
Engineered for versatility and precision, the downlight is available in a 6-inch size and built to meet stringent standards including CSA, UL, NSF, and optional IP64/IP65 ratings, with ISO 3 cleanroom compatibility. It offers multiple color temperature options from 2700K to 5000K, and high color rendering choices of 80+, 90+, and 97+ CRI to ensure accurate color representation and a pleasant visual environment. As a specification-grade recessed LED fixture, it supports installation in grid, drywall, or cleanroom ceilings, with delivered lumen packages ranging from 1000 to 5000 lumens. The fixture includes a standard sealed regressed lens for effective glare control, with an optional smooth, flush wipe-down lens available for applications requiring easier cleaning and enhanced sealing. NSF2 Splash Zone Certification and IP64 or IP65 ingress protection ratings make it suitable for environments requiring stringent hygiene and moisture control. Trims are finished with antimicrobial coatings to reduce the risk of bacterial growth and are available in matte or gloss white finishes.
The fixture’s install frame is constructed from 18-gauge rigid steel and supported by two butterfly-style vertically adjustable brackets. It incorporates a large junction box with five ½-inch trade-size knockouts for wiring flexibility and includes a plaster ring attachment that allows post-installation adjustment from below the ceiling for applications up to 2.5 inches thick. Die-cut, closed-cell EPDM foam gaskets ensure a tight seal between the lens, trim, and reflector, maintaining the fixture’s integrity against airborne contaminants.
The optical assembly is factory sealed to preserve a clean, professional appearance. The heat sink, reflector, lens, and trim are bonded using long-life EPDM gasket materials and supported by torsion springs for secure attachment to a vertically adjustable collar. The standard regressed lens is a clear, spherical, high-impact polycarbonate element sealed within the reflector assembly to maintain a dust-free optical chamber. It features a die-cast, gasketed trim that seals tightly to the ceiling surface, offering smooth, easily cleanable external surfaces. For applications requiring a completely flush surface, an optional flat polycarbonate lens is available, sealed directly to the trim at the roomside plane for IP65-rated protection.
The fixture’s light source is a factory-sealed, COB-style LED engine that is both field replaceable and serviceable from below. These high-efficiency LEDs deliver consistent color performance with tight 2 SDCM color binning and are available in color temperatures ranging from 2700K to 5000K. Users can select from 80, 90, or 95 CRI options to meet specific visual or clinical lighting needs. The LED engine provides a long lifetime exceeding 60,000 hours at L70, ensuring reliability and minimal maintenance over time.
The electrical system features a programmable, constant-current electronic driver that offers dimming control down to 1% using a 0–10V protocol. It operates efficiently with greater than 85% efficiency and less than 10% total harmonic distortion, and it meets FCC Part 15, Class A standards. The driver is available for 120–277V or 347V AC, 50/60Hz power input, with optional DALI-compatible configurations for advanced control integration.
Trim finishes undergo a rigorous five-stage pretreatment process and are coated with an antimicrobial polyester powder finish in matte white as standard, with gloss white available upon request. The fixture is designed for recessed Non-IC installations and is compatible with multiple ceiling types, including 9/16”, 15/16”, 1”, and 1-1/2” T-bar grids as well as drywall systems. The plaster ring provides vertical adjustment for ceiling thicknesses from ½ inch to 2.5 inches and is intended for use beneath a covered structural ceiling.
The 6" patient room LED downlight meets ETL certification for recessed Non-IC applications and wet locations. Depending on the lens configuration, it offers IP64 protection for regressed lens versions or IP65 for flush lens models. Additionally, it holds NSF certification for splash zone applications and is ISO-3 cleanroom rated when configured with FSL or FSS trim styles. This combination of elegant design, cleanroom-grade construction, and superior optical performance makes it a trusted lighting solution for healthcare environments prioritizing comfort, cleanliness, and reliability.
