Quartz glass tube UV-C lamp for germicidal applications. Operates with incandescent lamp or capacitor-based circuit connected directly to 220 V / 50 Hz or 120 V / 60 Hz mains without ballast. Rated for up to 20,000 switching cycles. Emits ultraviolet light at 254 nm wavelength, which disrupts the DNA/RNA of microorganisms, inhibiting replication and achieving disinfection. Effective against bacteria, viruses, and other microorganisms in air and water within seconds. Particularly useful where conventional chemical disinfection methods (e.g., chlorination) are less effective. Suitable for use in small-scale disinfection devices such as air purifiers, refrigerators, humidifiers, sterilizers, dental equipment, and washing machines. Type: No ozone generation Voltage: 10 V DC Power: 3 W Operating tube voltage: 9.5–13 V DC UV irradiance at 254 nm: ≥30 µW/cm² at 30 cm distance Lifespan: 9,000 hours Color: Silver + transparent Material: Quartz glass + metal alloy Dimensions: Length 56 mm, Diameter 16 mm Package includes: 2 × UV-C bulbs Note: Product color may vary slightly due to lighting and screen settings. Slight dimensional variance (±1–3 mm) may occur due to manual measurement.
