Quartz glass construction; compatible with incandescent lamp or special capacitor systems operating at 220 V / 50 Hz or 120 / 60 Hz line voltage without ballast; switch rated up to 20,000 cycles. Emits ultraviolet UVC light that disrupts the structure of viruses and other microorganisms, rendering them unable to reproduce and effectively eliminating them. UVC radiation can inactivate microorganisms in air and water within seconds. Ultraviolet lamps are particularly effective against pathogens that are resistant to conventional chemical disinfection methods. Suitable for small-scale applications such as air purifiers, microwave ovens, refrigerators, sterilization devices, humidifiers, dental instruments, and washing machines. Type: Ozone / No Ozone. Voltage: 10 V. Power: 3 W. Operating voltage: 9.5–13 V. UV radiation intensity at 254 nm: greater than 30 μW/cm² at 30 cm distance. Service life: 9,000 hours. Color: Silver + transparent. Material: Quartz glass + alloy. Dimensions: Length: 56 mm; Diameter: 16 mm. Package includes: 1 x UVC Bulb. Other items not included. Note: Lighting and display settings may cause slight variations in color representation. Measurement tolerance: ±1–3 cm.
