Certolux CRUi Red & Amber LED Luminaires – Recessed Cleanroom LED Fixtures with Inset Doorframe
Certolux’s CRUi Red and Amber LED Luminaires are a high-performance solution for recessed lighting in critical cleanroom lighting environments. Built for ISO Class 3–8 applications, it combines durability, precision, and compliance with stringent standards. Its IP65 rating ensures dust-tight protection and resistance to water jets, making it ideal for wet locations and high-pressure washdowns up to 2500 psi. Available in red or amber LED configurations or combined with white LEDs, the CRUi series delivers reliable illumination tailored to specialized requirements.
Lighting quality in cleanrooms directly impacts operational accuracy and safety. The CRUi series addresses this with narrow spectrum LED options, including pure red (635 nm) and amber (604 nm) wavelengths, ensuring minimal UV output and precise color purity. These features support sensitive processes in pharmaceutical, biotech, and food-grade facilities where contamination control is critical. The luminaire’s triple-gasket system, featuring silicone seals and Poron gaskets creates an airtight barrier against particulates, while its smooth acrylic lens simplifies cleaning without compromising optical performance.
Designed for flexibility, the CRUi series supports both T-bar grid and flanged installations, meeting NEMA LE4 Type G standards. Optional plenum access panels allow serviceability from the room side, reducing downtime and maintaining compliance in controlled environments. The housing is precision-formed from cold-rolled steel with a five-stage pretreatment and polyester powder coating for corrosion resistance. Stainless steel and aluminum options are available for enhanced durability. With tunable white ranges (2700K–6500K) and dimmable drivers down to 1%, the CRUi series ensures optimal lighting control for diverse cleanroom tasks.
Every detail of the CRUi luminaire reflects a commitment to performance and reliability. From CSA and UL certifications to NSF2 compliance for food zones, this fixture meets the highest industry standards. Its modular LED boards deliver over 60,000 hours of L90 life, ensuring long-term efficiency and reduced maintenance costs. For facilities requiring specialized lighting such as biosafety labs or pharmaceutical production, the CRUi series offers a proven solution that balances precision, durability, and ease of integration.
Discover the next generation of switchable RED LED luminaires, engineered to help support natural sleep–wake cycles while still delivering ample illumination for critical visual tasks. Ideal for:
- Professionals working in medical and research laboratories
