The 8" cleanroom LED downlight is a recessed round aperture fixture suitable for critical environments including Cardiac Cath & EP Labs, Cleanrooms, Food Service areas, Hybrid Operating Rooms, Labor & Delivery, Laboratories, Natatoriums, Neonatal ICUs, Operating Rooms, Patient Rooms, and Veterinary facilities. The fixture supports a nominal lumen output ranging from 2500L to 6500L with three selectable beam spreads. It carries an IP65-rated option, NSF-rated option, ISO 5/Class 100 Cleanroom certification, and Chicago Plenum approval. The light source is LED – Static White, with color temperatures of 2700 K, 3000 K, 3500 K, 4000 K, 5000 K, and optional color filters, delivering CRI 80+ standard or 90+ with the -HC option, which incurs a 15% lumen reduction. Wattages range from 36.9 W to 72.9 W, and the fixture operates on 120 or 277 V. Lighting control options include 0-10V, DALI, DMX, Lutron Athena, and Lutron EcoSystem, while emergency options include integral battery backup, remote battery backup, and remote inverter. The fixture employs a regressed lens with flare trim for precise optical control and light distribution, and its shallow 5-5/8" depth allows installation in restricted plenums. The downlight is suitable for installation in covered interior or exterior ceilings using fire box or new construction setups.
The thermal management system includes an aluminum heat sink and components rated for cool operation, long life, and minimal maintenance. The fixture also incorporates a thermal protector for insulation detection per UL/NEC standards, with input voltage specification required. The internal LED driver supports indoor and outdoor conditions from -30°C to 60°C (-22°F to 140°F), with 0-10V CCR 10% dimming standard and load-insensitive operation at 120–277V, 50–60 Hz. The trim assembly consists of rustproof, grooveless, smooth, self-flanged white aluminum with a Kirlin BioGard antimicrobial finish, which continuously inhibits bacterial growth on the trim coating. The regressed tempered prismatic spread lens, IP65-sealed and gasketed, incorporates liquid silicone seals between trim and lens, closed-cell housing flange gasketing, closed-cell trim flange gasketing, bottom pan gasketing, and O-rings on stainless steel fasteners to ensure a secure, contamination-resistant installation.
The acrylic enameled aluminum housing is rustproof and corrosion resistant, exceeding 1000 hours in the ASTM 5% salt spray test. Its shallow depth fits restricted plenums while maintaining cool operation to extend component life. The modular design allows full visibility and servicing through the aperture, with a built-in plaster flange for seamless ceiling integration. The UL-listed galvanized steel outlet box includes a 14 GA insulated, removable cover with ½" and ¾" knockouts. Installation supports indoor and outdoor ceilings up to 1 1/8" thick and is compatible with fire-rated enclosures provided by others. Two 27" hanger bars and adjustable brackets are supplied for mounting. The fixture meets UL and C-UL (Canada) listings for wet, damp, or dry locations in covered ceilings, supports through-branch conductors up to four #12 AWG 90°C, and complies with IEC/EN 60601-1-2 electromagnetic compatibility standards for medical electrical equipment. It is FCC Part 15 certified for EMI/RFI emissions, ensuring performance in sensitive cleanroom, laboratory, and medical environments.
