To build cost-effective disinfection equipment for competitive global consumer markets, purchasing a Standard 4P UV Lamp from reliable China factory suppliers is a practical choice. Kingrate manufactures these standard-output lamps using high-transmittance quartz glass to ensure a steady and reliable UVC output field. The compact 15mm tube diameter and broad AC 85V-265V operational voltage range allow global appliance manufacturers to easily integrate these lamps into residential air sanitizers and under-sink water purifiers.
High-Purity Anti-Solarization Quartz Glass: Adopts high-transmittance pure quartz material, which effectively resists UV solarization aging, avoids clouding and purple discoloration of ordinary soft glass, and maintains stable 253.7nm UVC transmittance throughout the 8000-hour service life.
Low Heat Generation Balanced Design: Operates at a standard 425mA current, with moderate power and low heat generation. It solves the overheating problem of small closed sterilization chambers, avoids thermal accumulation in static water and narrow air ducts, and is safer and more energy-saving for household and light commercial scenarios.
Global Wide-Voltage Compatibility: Standard 4P UV Lamp supports AC 85V-265V full-range voltage adaptation, compatible with regional power grids worldwide, reducing customized configuration costs for international distributors.
• Residential Under-Sink Water Filtration: Placed within stainless steel sterilization chambers to provide a final germicidal barrier for home drinking water.
• Residential HVAC Induct Units: Installed inside home air ducts to clean circulating air and prevent mold buildup on central air conditioning coils.
• School and Office Air Sanitizers: Integrated into mobile air purification carts to maintain clean air in classrooms and shared workspaces.
1. Cut off the equipment power supply completely before installation and maintenance to ensure electrical safety.
2. Align the 4-pin ceramic base with the socket, insert smoothly and vertically to avoid bending the pins and causing poor contact.
3. Wipe the quartz tube with alcohol regularly every month to remove dust and oil stains and maintain UVC output efficiency.
Power: Depending on the model, the power range is between 4W and 80W
Wavelength: 253.7nm
Lamp size: diameter is about 15mm, and the length varies according to the model
Working voltage: AC 85V-265V
Working temperature: -20°C to 50°C
• High-Vacuum Automated Exhaust: Low-cost factories often use manual exhaust pumps, which can leave trace moisture or ambient air inside the tube. This contamination causes the internal arc to flicker and shortens the lamp's life. Kingrate uses automated high-vacuum exhaust lines to purge every tube completely before gas filling, ensuring a clean plasma arc and reliable electrical performance.
• Consistent Quartz Purity: We source only premium, high-purity quartz glass for our tubes. This ensures the glass maintains Standard 4P UV Lamp‘s high UVC transmittance over time, preventing the rapid solarization and drop in output common to cheaper soft glass alternatives.
To assist high-volume manufacturing clients during the product development phase, Kingrate offers a dedicated engineering evaluation support program. We can provide custom sample lamps tailored to match the starting current and electrical profile of your specific prototype ballasts, allowing your team to verify performance and compatibility before committing to a full production order.
A: While magnetic ballasts can ignite the Standard 4P UV Lamp, we highly recommend using a high-frequency electronic ballast. Electronic ballasts operate at much higher frequencies (typically >20kHz), which eliminates strobe flickering, improves energy efficiency, and extends the operational life of the lamp compared to older magnetic models.
A: No. Because this lamp is designed with ozone-free quartz glass that filters out the 185nm wavelength, it does not produce ozone gas or any associated chemical odors. Any slight odor during initial operation is typically caused by dust or oils on the glass surface being heated; cleaning the lamp before installation prevents this.
A: Touching the glass leaves skin oils behind, which can burn onto the quartz surface during operation, creating localized dark spots. These patches block UVC light and trap heat, which can crack the glass over time. If accidental contact occurs, clean the tube thoroughly with an isopropyl alcohol wipe before powering it on.
