For building cost-effective biological sterilization systems, direct factory procurement of Kingrate PL-S Series H-Shaped UV Lamp PL-S9W is the optimal solution. Adopting proprietary internal protective coating technology, this lamp extends the filament stable service life up to 13,000 hours, reaching top global industry standards and greatly saving customer maintenance labor and replacement costs.
• Ultra-High UVC Transmittance: PL-S Series H-Shaped UV Lamp PL-S9W adopts high-purity dehydroxylated quartz glass, with effective UVC light transmittance of over 90%, maximizing germicidal efficiency.
• Superior Anti-Aging Stability: Equipped with proprietary internal protective coating to resist solarization and light decay. It maintains high UVC output stability even after 9,000 hours of long-term operation.
• High Structural Uniformity: Strict dimensional tolerance control (145mm length, 12mm diameter) supports automated assembly for OEM equipment manufacturers with zero installation mismatch.

Water Treatment: It’s got you covered! Use it for drinking water disinfection, wastewater cleanup, or keeping pools, fish tanks, and fish farms germ - free. Stick it in your home water dispenser? Every glass stays bacteria - free. Got a small fish tank with tropical fish? Add this lamp, and your water stays clear, no weird smells, and fish stay healthy. Small fish farms? Use it to disinfect their water systems—fewer fish getting sick, better yields and quality.
Air Purification: Perfect too! Busy hospital wards, lab rooms—germs love to float around there. The PL-S Series H-Shaped UV Lamp PL-S9W zaps those germs fast, so doctors, nurses, and lab folks can breathe easier. Even your home or office AC—after running a while, it gets dusty and germy. Pop this lamp in, and the air from your AC gets cleaner, cutting down on sneezing or coughing fits.
Industrial Disinfection: A must - have for spots like food plants, pharma factories, breweries—anywhere hygiene is top - tier. Use it to disinfect equipment and materials. A bakery’s production gear (touching food daily)? This lamp cleans it safely, no chemicals needed. Pharma factories? Sterilize medicine bottles with it to stop cross - contamination. Breweries? Disinfect fermentation tanks and bottling lines—no unwanted bacteria, so your beer tastes consistent, every time.
Slight brown discoloration is normal aging cathode sputtering after long-term use. Rapid brown ring formation within hundreds of hours of use indicates excessive starting current, which is caused by unregulated or mismatched ballasts.
Yes. The PL-S Series H-Shaped UV Lamp PL-S9W itself is not waterproof. Direct water contact will cause excessive cooling of the lamp tube and short circuit of the exposed G23 pins. A matched waterproof quartz sleeve is mandatory for underwater installation.
For dusty HVAC environments, wipe the quartz tube with isopropyl alcohol every 3 months. Dust accumulation will absorb UVC radiation and significantly reduce sterilization efficiency.
Our core team has devoted over 20 years to special light source research and holds multiple invention, utility model, and design patents. We use high-transmittance quartz glass and proprietary manufacturing processes to achieve lamp lifetimes of 8,000–13,000 hours, with end-of-life light decay below 30% – performance comparable to world-class brands. Our products are fully certified with CE, RoHS, REACH, FCC, and ISO9001, offering compliance assurance for your global sales. We go beyond parameter leadership; we focus on stable and reliable performance in real-world applications (air disinfection, water treatment, surface sterilization, VOC degradation, etc.). This is the fundamental reason why leading industry clients continue to reorder from us.
