Upgrade your HVAC system with this high-output 36W UV bulb, designed to deliver more effective UV disinfection than standard 6-25W lamps—without generating ozone. It emits 253.7 nm short-wave ultraviolet light that sterilizes HVAC ducting and AC systems, so the air moving through your space stays cleaner. Safety is built in from the start: ETL listed for safe use, CARB certified, and fully compliant with California's ozone emissions limit, it keeps ozone levels below 0.05 ppm—equivalent to zero ozone—so you can run it with confidence when used as intended. Setup couldn't be simpler. The ballast wires connect directly to your HVAC wiring terminal for seamless power integration, and the unit can be secured with screws or foam tape, giving you flexible mounting options. Built to perform day in and day out, it features a 2G11 4-pin ceramic base and quartz glass construction that provides clear UV light transmission while enhancing longevity for continuous use. By reducing contaminants within circulated air and on the internal components of AC systems, it supports a cleaner environment wherever it's installed—making it a smart fit for HVAC systems in schools, hospitals, hotels, offices, and more.
