The 4" BDL LED downlight is purpose-built for acute behavioral health facilities, blending robust safety features with a warm, non-institutional aesthetic. Designed to create a comfortable and secure environment, this fixture delivers the durability and tamper resistance required in behavioral health settings while maintaining a refined residential appearance. Its specification-grade construction features a sealed, vandal-resistant housing engineered to endure high abuse, and it is tested to IK10—the highest impact resistance rating. Beyond strength, it also meets NSF2 certification standards for cleanability, carries an IP65 ingress protection seal, and includes antimicrobial finishes to support hygiene in sensitive care environments. The fixture’s ligature-resistant design minimizes the risk of self-harm, ensuring a safer, more therapeutic space for patients and staff alike.
Ideal for hospitals, nursing homes, behavioral health facilities, and patient rooms, the 4" BDL downlight offers flexible performance in a compact form. It delivers between 1000 and 5000 lumens of output with smooth dimming to 1%, providing adaptable light levels for various healthcare applications. Available in multiple color temperatures from 2700K to 5000K, and with CRI options of 80+, 90+, or 97+, the fixture ensures accurate color rendering and visual comfort. Certified to CSA and UL standards, it is rated IP65 for wet locations and NSF2 Splash Zone for enhanced durability in demanding medical settings.
The fixture’s installation frame is constructed from 18-gauge rigid steel for dependable structural integrity and supported by two universal-style, vertically adjustable brackets. A large junction box is integrated into the frame, featuring five ½-inch trade-size knockouts for versatile wiring configurations. The plaster ring attachment allows post-installation adjustment from below the ceiling, accommodating ceiling thicknesses up to 2.5 inches and simplifying integration with both security metal and hard ceiling types.
Its optical assembly is factory sealed to maintain a clean, tamper-resistant design. The heat sink, reflector, lens, and trim are sealed with long-life EPDM closed-cell gaskets to preserve optical clarity and ensure a sterile surface. All components are secured using tamper-resistant Torx screws and supported by a vertically adjustable collar. This robust assembly ensures long-term reliability while preventing unauthorized access or tampering in behavioral health environments.
The standard lens is a flat, clear, 0.125-inch-thick, high-impact polycarbonate panel, sealed within the trim assembly and reinforced by a die-cast ring that provides continuous compression across the lens, reflector, and gaskets. Its smooth, flat exterior surface allows for easy cleaning and disinfection—an essential feature for healthcare settings requiring strict hygiene standards. The result is a lens system that withstands heavy use while maintaining optical integrity and a sleek appearance.
At the heart of the fixture is a factory-sealed, COB-style LED light engine that is both field replaceable and serviceable from below, ensuring ease of maintenance without ceiling access. The LED engine delivers high efficiency and precise color consistency, offering 2 SDCM uniformity across all color temperatures. Users can select from 2700K, 3000K, 3500K, 4000K, and 5000K options with a lifetime exceeding 60,000 hours at L70. The fixture maintains excellent color accuracy with standard 80 CRI and optional 90 or 95 CRI configurations to meet specific healthcare lighting requirements.
The electronic driver is constant current, programmable, and dimmable to 1% using a 0–10V protocol for precise lighting control. With an efficiency greater than 85% and total harmonic distortion below 10%, the driver ensures reliable performance and smooth dimming. It operates on 120–277V or 347V at 50/60Hz, certified to FCC Part 15, Class A, and is available with optional DALI compatibility for advanced control systems.
The trim finish undergoes a five-stage pretreatment process before being coated with an antimicrobial gloss white polyester powder, providing a durable, sanitary surface resistant to microbial growth. For design flexibility, an antimicrobial matte white finish is also available. Both finishes ensure long-term cleanliness and durability while contributing to a visually calm and welcoming environment.
Installation versatility is a key design consideration. The fixture is suitable for recessed Non-IC applications and compatible with 9/16", 15/16", 1", and 1-1/2" T-bar grids as well as drywall ceilings. The plaster ring allows vertical adjustment to accommodate ceiling thicknesses between ½ inch and 2.5 inches. Designed for use beneath a covered structural ceiling, this downlight integrates seamlessly into both standard and secure ceiling systems common in healthcare and behavioral health facilities.
The 4" BDL LED downlight is ETL listed for Non-IC recessed applications and rated for wet locations. It features IP65 ingress protection for its sealed optical chamber, ensuring complete protection against dust and water jets. With NSF2 Splash Zone certification, IK10 impact resistance, and antimicrobial finishes, it is ideally suited for behavioral health spaces where safety, hygiene, and durability are critical. Balancing rugged construction with a comforting, non-clinical aesthetic, this fixture exemplifies how thoughtful engineering and human-centered design can create safer, more therapeutic healthcare environments.
