Upgrade your indoor air quality with this 72W UV light designed for HVAC ductwork and AC systems. Emitting 253.7 nm short-wave ultraviolet light, it helps sterilize HVAC interiors and reduce contaminants in circulating air and system components, supporting a cleaner environment. With a higher output than standard 6–25W UV lamps, it delivers effective UV disinfection without generating ozone. ETL listed for safe use and CARB certified to meet California’s ozone emissions limit, it maintains ozone levels below 0.05 ppm, equivalent to 0 ozone, when used as intended. Installation is straightforward: connect the ballast wires directly to the HVAC wiring terminal for seamless power integration, then secure the unit with screws or foam tape to suit your mounting needs. Built for reliable, continuous operation, the lamp features a durable 2G11 four-pin ceramic base and quartz glass that allows clear UV light transmission while supporting long-lasting performance. Suitable for HVAC systems in schools, hospitals, hotels, offices, and other commercial environments, this UV light helps reduce contaminants within air circulation pathways and internal AC components to support a cleaner indoor environment.
