The Wall Mount Cylinder Light with Care222® UV Technology integrates far-UVC disinfection with precision optical design and architectural-grade construction for safe and effective use in occupied spaces. This luminaire employs a UV wavelength range of 200nm to 230nm, with a peak emission at 222nm, classified as far-UVC. The patented short-pass filter ensures a narrow 222nm band, effectively removing longer UV wavelengths that could penetrate living tissue or the upper layers of the cornea, making the system safe for continuous operation around people when installed according to guidelines.
The UV lamp module is mercury-free and designed for long-term use, rated for 3,000 hours, roughly equivalent to five years of typical operating time. It operates on 12-minute cycles, with each cycle running between 10 and 50 seconds depending on the application’s target dose, eliminating the need for external controls or startup commissioning. When illuminated, the module emits a soft violet glow from a compact 1.75" x 2.38" opening, providing visual confirmation of operation without compromising safety.
The optical assembly features a Bounding Ray™ design with a 65° cutoff to source and source image, minimizing glare and enhancing visual comfort. Top-down flash characteristics further reduce distractions while providing a Medium Wide 1.0 S:MH distribution as standard. Color performance is consistent, with a 2.5-step MacAdam ellipse, 80 CRI typical, and optional 90+ CRI for high-fidelity applications. This luminaire meets A+ standards, ensuring chromatic consistency, color rendering, and color temperature tolerance out of the box, and integrates seamlessly with Acuity Brands control products for simplified commissioning and control.
Construction emphasizes durability and thermal management. The cylinder is built from heavy-gauge aluminum with an extruded flangeless reflector that allows passive airflow, promoting efficient heat dissipation. The surface-mounted wall cylinder installs directly to 4" recessed or surface octagonal junction boxes, and optional field-configurable conduit covers match the cylinder’s finish and diameter for aesthetic continuity. The wall mount can be oriented up or down, providing flexibility for different mounting scenarios.
Control options include compatibility with nLight® wired and nLight AIR® wireless networks, with integral power supply modules shipped as remote add-ons. The luminaire supports visible light integration with filtered far-UVC 222nm modules in hybrid or UV-only configurations. A companion visible-light-only option is also available. Electrical operation is supported from 120VAC to 277VAC at 50 or 60 Hz ±3 Hz, with support for 347V via a remote step-down transformer. Power factor exceeds 0.9%, and the UVC module requires an unswitched circuit intended for continuous operation. Single-circuit operation is recommended; wall switches are not compatible.
Care222® UV disinfection technology disrupts DNA and RNA in pathogens, preventing reproduction and effectively inactivating harmful microorganisms. It operates continually while maintaining safety standards established by the American Conference of Governmental Industrial Hygienists (ACGIH®), allowing occupants to remain in the space during operation when installed and used according to instructions. The combination of safe far-UVC emission, consistent color rendering, configurable optics, and reliable construction makes this wall mount cylinder an effective solution for pathogen mitigation in occupied commercial, healthcare, and educational environments.
