CureUV Brand UVC Bulb for Cuno APUV-12

4 Pin on a Single End - 39 Watt Germicidal UVC Bulb

Our CureUV brand Replacement UVC Light Bulb for Cuno APUV-12 is a 39-watt germicidal water treatment bulb. With 4 pins on a single end, this germicidal UVC light bulb features a peak UV output of 253.7nm. This wavelength region comes under maximum germicidal effectiveness and is highly fatal to microorganisms such as bacteria, viruses, protozoa, and other pathogens.

When water is passed through the CureUV’s germicidal UV light, it deactivates the genetic material of the microorganism and renders them incapable of multiplying. This high-quality fixture has a lifespan of up to 10,000 hours and is set inside non-ozone glass. The UVC light bulb comes with 12 months of sterilizing property after which it must be replaced for maximum effectiveness. With the CureUV Brand UVC Bulb, you can always be sure that your water is clean and safe.

This bulb is available with a shatterproof coating that in case of damage keeps the lamp glass from falling into the unit where is installed. This results in an easy way to dispose of glass if it shatters. You can select this shatterproof option above.

Do I need shatterproof coating?

Although shatterproof coating can lower the intensity of the UV-C bulb by as much as 15%, it is recommended for applications in which it is crucial to avoid potential glass breakage at all costs. These applications include but are not limited to food processing and medical institutions. However, if glass breakage would be inconvenient but not catastrophic, skipping the costly shatterproof coating is quite alright. After all, we do not use shatterproof coating with our glasses and plates at home.
