This specification-grade recessed cleanroom LED luminaire is designed for demanding healthcare, laboratory, and contamination-controlled environments where strict cleanliness, moisture protection, and durability are essential. Available in red or amber LED configurations, it features a precision-engineered inset doorframe that seals directly to the housing to maintain a fully enclosed, contamination-free barrier. The fixture is triple gasketed, IP65 certified, and rated for ISO Class 3 through ISO Class 8 cleanrooms. Its robust construction supports 2500 psi washdown performance, making it suitable for wet locations, food processing zones, and high-hygiene areas that require frequent cleaning. Certified to NSF2 standards for food, splash, and non-food zones, it ensures superior performance in both healthcare and industrial cleanroom settings.
The housing is precision formed from one-piece, seam-welded, 20-gauge cold-rolled steel, designed with a hole-free surface to eliminate contamination traps. A rigid 18-gauge flange with welded, rounded corners enhances strength and safety. For enhanced durability and corrosion resistance, stainless steel and aluminum housing options are also available. Each fixture undergoes a five-stage pretreatment process followed by a gloss white polyester powder coating, meeting ASTM B117 standards with 1,000-hour salt spray testing for proven longevity in harsh conditions.
The inset one-piece door frame is fabricated from 18-gauge cold-rolled steel and constructed with welded corners for rigidity. Captive, countersunk, stainless steel flat-head fasteners with integral silicone O-rings ensure a secure, watertight seal, while stainless steel aircraft cables allow the door to hinge open safely for maintenance. The door frame is reversible and removable, making service access simple. A high-performance Poron™ gasket provides a continuous seal between the doorframe and housing to prevent air and particle infiltration.
The standard optical assembly includes a 0.125-inch thick high-impact clear acrylic lens with a diffuse inner layer that delivers symmetric light distribution (DSA). The lens features a smooth outer surface for easy cleaning and maintenance in cleanroom environments. It is sealed to the doorframe using RTV silicone sealant and secured with continuous perimeter brackets for complete gasket integrity. Optional lens materials and distributions are available depending on specific application requirements.
Triple gasket protection ensures superior sealing at every interface. The lens is secured to the doorframe with 100% pure silicone RTV sealant, while the doorframe itself is sealed to the housing with a resilient, chemical-resistant CertaSeal microcellular closed-cell gasket. Additionally, the housing-to-ceiling interface is sealed using a closed-cell neoprene gasket, and each door screw is equipped with a silicone O-ring and specially designed sealing flat-head screws for redundant protection against dust, moisture, and contamination ingress.
The luminaire’s LED modules are engineered for reliability and color stability, maintaining consistent CRI and lumen output across a long operational life. Available color temperatures include 3000K, 3500K, 4000K, and 5000K, each with a 3-step SDCM color consistency and a standard CRI of 80, with an optional 90 CRI version for color-critical environments. A tunable white option offers an adjustable CCT range from 2700K to 6500K for flexible task or ambient lighting applications. Field-replaceable LED modules are commercially available and designed to achieve an L90 lifetime greater than 60,000 hours. Red and amber LED arrays can be used independently or in combination with white LEDs, providing tailored spectral output for sensitive environments requiring reduced UV or blue light exposure.
The fixture’s electrical system incorporates a programmable, constant-current electronic driver that is dimmable to 1% via 0–10V control. It operates at an efficiency above 85% with total harmonic distortion under 10%, meeting FCC Part 15, Class A standards. It supports universal voltage inputs (120–277Vac or 347Vac, 50/60Hz). Optional driver configurations include Lutron™ or DALI compatibility, and internal emergency drivers can be serviced from the room side. Each LED color channel is independently circuited for precise control and redundancy.
Installation versatility is ensured with a universal mounting system compatible with both 1.0-inch and 1.5-inch T-bar grid ceilings, as well as flanged ceiling types. Swing-style mounting brackets support flange installation, offering a vertical adjustment range from 1.3 to 2.9 inches for easy alignment. Grid installation adheres to NEMA LE4 Type G standards, with an option available for 2-inch T-bar systems. Ambient operating temperatures range from -4°F (-20°C) to 104°F (40°C), supporting operation in a wide variety of controlled environments.
This recessed LED cleanroom fixture is UL listed for wet locations under covered ceilings in both the U.S. and Canada (ANSI/UL1598 and UL8750). It is classified as Type IC for insulated ceiling compatibility and certified to NSF2 for food, splash, and non-food zones. The design meets IEC60529 IP65 requirements, ensuring complete dust tightness and resistance to water jets. It complies with ISO Class 3–8 cleanroom standards and meets EU GMP Grade A criteria, suitable for biosafety levels BSL1–2. For facilities requiring higher containment, a variant with an overlapping door is available for BSL1–3 compliance. The fixture also meets CCEA requirements and is rated for rigorous 2500 psi washdown applications, making it an ideal lighting solution for sterile, medical, and laboratory environments requiring the highest standards of cleanliness, protection, and performance.
