Designed to emit ultraviolet light with a peak wavelength of 253.7 nm, these bulbs provide chemical-free UV treatment that does not alter taste, odor, pH, or the general chemistry of water. Each lamp is engineered to match the physical dimensions and electrical requirements of OWS-12\/121\/124\/12T fixtures and the OWS-455EB\/OWS-12EB ballasts for straightforward swap-in replacement.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these UV tubes work inside my water system?\u003c\/h3\u003e\n\u003cp\u003eThese lamps produce germicidal UV-C light at the peak wavelength of 253.7 nm, which inactivates microorganisms in flowing water without adding chemicals. The process is purely physical and leaves no residual taste, odor, or chemical change in the treated water. For consistent performance, lamp output and the quartz sleeve cleanliness must be maintained according to schedule.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003ePeak wavelength: 253.7 nm for UV-C germicidal action\u003c\/li\u003e\n  \u003cli\u003eOperation is chemical-free and does not change water chemistry\u003c\/li\u003e\n  \u003cli\u003eWorks inside the HQUA UV chamber; requires clear quartz sleeve for effective transmission\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat are the installation and compatibility details?\u003c\/h3\u003e\n\u003cp\u003eThe HQUA-OWS-12L lamp is 36.4 inches long with a 0.6-inch diameter and a 4-pin standard base, making it physically compatible with OWS-12\/121\/124\/12T housings. It runs at 40W and 425 mA and is designed to function with OWS-455EB and OWS-12EB ballasts.

The sleeve can accumulate scale or film that reduces UV transmission; cleaning restores lamp effectiveness. Replace the quartz sleeve itself approximately every 24 months or sooner if damaged.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eReplace lamp annually for best germicidal output\u003c\/li\u003e\n  \u003cli\u003eClean quartz sleeve every 6–12 months to maintain UV transmission\u003c\/li\u003e\n  \u003cli\u003eReplace quartz sleeve about every 24 months or if compromised\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhere can these HQUA UV tubes be used?\u003c\/h3\u003e\n\u003cp\u003eHQUA germicidal lamps are suitable for a range of water treatment contexts, from household purification to industrial and wastewater reuse applications. They appear in residential systems to improve daily water safety, in industrial settings for process or cooling water, and in reuse projects to reduce pollution and conserve resources. Use within the lamp’s intended system ensures proper exposure and performance.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eResidential point-of-entry and point-of-use HQUA OWS-12 systems\u003c\/li\u003e\n  \u003cli\u003eIndustrial water supplies like irrigation, aquaculture, or production cooling\u003c\/li\u003e\n  \u003cli\u003eWastewater reuse applications where UV treatment is specified\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for?
