The SAF series by Certolux is a specification-grade recessed flanged LED troffer designed to meet the stringent demands of cleanroom and hazardous location environments. Engineered for precision and reliability, this IP66, IC-rated luminaire is suitable for ISO Class 4 cleanrooms and available in multiple configurations, including 1x4, 2x2, and 2x4. Its robust construction and sealed design make it ideal for pharmaceutical manufacturing, food processing, life sciences, and laboratory environments, where contamination control and durability are paramount. The fixture meets NSF/ANSI 2 standards for Food Zone Non-Contact and Splash Zone applications, ensuring compliance in sanitary spaces. Rated for wet locations and insulated ceilings, the SAF series also supports Hazardous Location applications, including Class I Zone 2, Zone 22, Class I Division 2, Class II Division 2, and Class III. Each model can be configured to meet specific temperature codes and certification requirements for hazardous environments.
The fixture’s housing is precision-formed from one-piece, 18-gauge cold-rolled steel that is TIG welded to achieve exceptional rigidity and a clean, seamless appearance. Designed for durability and ease of maintenance, the SAF series employs a white polyester powder-coated finish that resists corrosion and maintains a cleanroom-compatible aesthetic. The mounting system uses swing-arm brackets with vertical adjustability, allowing the fixture to be mounted securely against the ceiling while maintaining a continuous, distortion-free seal to the plenum. This ensures a uniform gasket compression and minimizes air leakage, an essential feature for cleanroom installations.
The door frame assembly is meticulously designed to provide both precision and protection. Fabricated from 18-gauge cold-rolled steel with TIG-welded corners, the one-piece frame features a 60° beveled perimeter that enhances the fixture’s clean appearance and simplifies maintenance. The self-centering design uses locating studs for accurate alignment, while stainless steel aircraft cables retain the door when opened for service. The frame is secured to the housing using military-grade, flat-head stainless steel captive fasteners with integral silicone O-rings that provide superior sealing performance compared to standard Teflon bushings. Floating cage nuts enable smooth operation and prevent over-tightening, with built-in protective stops to safeguard against damage. Throughout the assembly, custom extruded closed-cell silicone gaskets with vulcanized corners create continuous, redundant seals between the door, housing, and plenum. This precision sealing system ensures long-term gasket integrity and prevents contamination ingress, while continuous retention mounts apply even pressure to both the diffuser and gasket for an airtight, dependable closure.
The lens system is equally robust, featuring a high-impact, 0.125-inch thick acrylic diffuser with a diffuse inner layer for uniform, symmetric light distribution. Its smooth external surface allows easy cleaning and resists particulate buildup, critical for maintaining cleanroom standards. The lens is permanently sealed to the door frame with RTV silicone sealant to maintain an IP66-rated barrier. Alternate lens materials and optical configurations are available to suit different application requirements.
Internally, the SAF series combines long-life LEDs with high-efficiency drivers to deliver reliable, consistent performance. The system is rated to provide an L80 lifespan exceeding 50,000 hours, maintaining stable output and color rendering throughout its service life. The fixture operates with a total harmonic distortion (THD) of less than 10%, ensuring electrical stability and compatibility with sensitive equipment. Standard dimming is provided through a 0–10V low-voltage driver with smooth 1% dimming capability, allowing precise control in environments requiring adjustable light levels. Optional emergency LED battery packs are available for critical operations requiring backup lighting, and red LED arrays can be integrated for specialty signaling or night-safe applications.
All electrical components are CSA or UL approved, confirming compliance with North American safety standards. The SAF series supports color temperatures of 3000K, 3500K, 4000K, and 5000K, with a CRI range of 80–89 to ensure accurate color rendering across medical, laboratory, and industrial settings. The luminaire delivers a range of lumen outputs from 1,000 to 10,000 lumens, allowing tailored illumination levels for diverse room sizes and ceiling heights.
Combining precision-engineered construction, comprehensive environmental protection, and versatile mounting options, the Certolux SAF series offers a cleanroom-grade lighting solution that excels in both performance and durability. Its integration of sealed housings, redundant gasket systems, and high-quality materials ensures reliable operation in environments where safety, cleanliness, and compliance are critical.
