LED - Patient Room 4” Downlight Luminaire

MDD-4

The MDD4 Patient Room Downlight is a purpose-built solution designed to elevate the quality and safety of healthcare environments. Engineered for reliability and aesthetics, this fixture integrates seamlessly into patient rooms, offering a clean, modern look without the institutional feel often associated with medical lighting. Featuring a sealed optical chamber, the luminaire ensures a hygienic installation by preventing contaminated air from entering the room, making it ideal for facilities prioritizing infection control. With lumen packages ranging from 1,000 to 5,000 and full-range dimming down to 1%, the MDD4 provides flexibility for both patient comfort and clinical tasks.

Built for demanding healthcare applications, the MDD4 combines advanced optical performance with robust construction. Its regressed clear polycarbonate lens is factory-sealed into the reflector assembly, maintaining a pristine optical environment while simplifying cleaning. Optional flush lens designs offer smooth wipe-down surfaces for areas requiring stringent sanitation. The COB LED light engine delivers exceptional color consistency and high efficacy, available in multiple color temperatures from 2700K to 5000K, with CRI options up to 95 for accurate color rendering. Lifetime performance exceeds 60,000 hours (L70), ensuring long-term reliability and reduced maintenance costs. The luminaire’s antimicrobial matte white finish further supports infection control protocols, while optional antimicrobial gloss finishes provide additional protection.

Electrical performance is equally impressive. The programmable, dimmable driver operates at high efficiency (>85%) with low THD (<10%), supporting 0-10V dimming to 1% and optional DALI compatibility. Certified to FCC Part 15 Class A, the MDD4 meets rigorous standards for electromagnetic compliance. Installation is straightforward, with compatibility for grid, drywall, and cleanroom ceilings, and vertical adjustment for ceiling thicknesses up to 2.5 inches. The fixture is ETL listed for wet locations, NSF Splash Zone certified, and ISO-3 cleanroom rated when paired with appropriate trim styles, making it a versatile choice for healthcare facilities seeking dependable patient room lighting.

Incorporating medical lighting best practices, the MDD4 delivers not only performance but peace of mind. Its ingress protection rating (IP64 for regressed lens, IP65 for flush lens) ensures durability in challenging environments. Combined with a five-year limited warranty, this downlight represents a smart investment for hospitals, clinics, and long-term care facilities committed to quality and safety.

The MDD4 Patient Room Downlight stands out as a superior solution for healthcare spaces, blending advanced optics, robust sealing, and flexible performance. Whether your priority is infection control, patient comfort, or long-term reliability, this luminaire delivers on every front. Explore how the MDD4 can transform your patient room lighting strategy.
