1. Quartz glass refers to ozone without ozone use incandescent lamp or special capacitor to connect to 220 V or 50 Hz or 120 or 60 Hz main voltage line without ballast switch up to 20,000 times2. It destroys the DNA structure of viruses, bacteria and other microorganisms, loses its ability to reproduce, and then kills viruses, bacteria and other microorganisms.3. Ultraviolet UVC can kill most bacteria and other microorganisms in air and water in a few seconds. Ultraviolet lamps can be particularly valuable in killing viruses that are difficult to kill with conventional chemical methods, such as chlorination.4. Application: Suitable for small applications such as air purifiers, microwave ovens, refrigerators, sterilizers, humidifiers, dental instruments, washing machines, etc. So on and so forth.Type: Ozone or No OzoneVoltage: 10 voltsPower: 3 WPipe voltage: 9.5-13 VUV radiation density 254nm30 cm, more than 30 cm2Service life: 9000 hoursColor: Silver and transparentMaterial: quartz and alloySize:Length: 56 mmDiameter: 16 mmPackage Contents:2 x UVC BulbOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
