The VRUo Series by Certolux is a vandal-resistant, specification-grade recessed luminaire engineered for environments requiring exceptional durability, safety, and controlled access. Designed with a plenum access feature, it allows maintenance personnel to reach the ceiling space directly through the fixture, enhancing serviceability without compromising security. The fixture is intended for installation in flanged, grid, or metal security ceilings, making it ideal for applications in high-security facilities, healthcare centers, behavioral health environments, and public spaces. Constructed with tamper-resistant fasteners and a security-grade lens system, the VRUo Series is tested to exceed IK10 impact resistance, ensuring it withstands heavy abuse and deliberate vandalism while maintaining consistent performance and visual integrity.
Precision die-formed and TIG seam-welded housing gives the fixture its exceptional structural strength and clean appearance, eliminating the need for post-grinding. Various housing materials and gauges are available to suit specific application requirements. The fixture’s mounting system accommodates multiple ceiling configurations: flange installations are supported by swing-style brackets, while grid-mounted versions are compatible with 1" and 1.5" T-Bar ceilings, with optional support for 2" T-Bar grids. The design also ensures compatibility with metal security ceilings, further expanding its use in controlled-access environments.
A defining feature of the VRUo Series is its sealed interior door system, which provides direct access to the plenum space. The door frame is a single precision die-formed piece, TIG welded at the corners for superior rigidity and sealed with closed-cell foam gaskets to prevent air, dust, and moisture intrusion. The door is secured to the housing with countersunk, tamper-resistant Torx® head fasteners with center pins, made of high-strength stainless steel. Stainless steel cables hinge the door to the housing, ensuring safe handling during servicing. The lens system is protected by continuous hold-down brackets and secured through heavy-duty thru-studs, delivering exceptional resistance to impact and preventing unauthorized removal.
For optical performance, the VRUo Series offers multiple lens options sealed to the door frame using a continuous retention system, with the lenses supported by stainless steel aircraft cables to ensure maximum safety and stability. The LED light source is available in three standard color temperatures—3500K, 4000K, and 5000K—and provides high visual comfort and consistency across a range of lumen packages from 3,500 to 24,000 lumens, depending on configuration. A night light option, available in white or amber LEDs, supports low-level lighting needs for continuous care or behavioral health applications.
The fixture’s electrical design emphasizes reliability and efficiency. High-quality LED modules are paired with precision drivers that maintain total harmonic distortion below 10%, supporting smooth 0–10V dimming control. The LED system achieves L80 performance exceeding 50,000 hours, ensuring sustained light output and color quality over time. All electrical components are CSA or UL approved, and a ½” EMT knockout is provided for wiring connections.
Finished in a durable polyester powder-coated white, the luminaire’s surface features a high-reflectivity coating that enhances optical efficiency while resisting corrosion and wear. With its sealed construction, plenum access functionality, and robust vandal-resistant design, the Certolux VRUo Series delivers long-lasting, low-maintenance performance ideally suited to correctional, healthcare, and high-security applications where reliability, safety, and tamper resistance are critical.
