The Purely UV - PUVLF435 UV Light Bulb For Germicidal Water Treatment is a guaranteed replacement bulb that has four-pin on a single end. The germicidal water treatment bulb is a 21 Watts light bulb that gives you a worry-free performance for an entire year. With a wavelength range of 253.7nm, the water treatment bulb has a total length of 17.7" and has an average span of 10,000 hours. The light bulb is 100% compatible with germicidal OEM Water sterilization filters, UV sanitizers, and water purifiers.
Since the light bulbs are intended to destroy microorganisms it is necessary to schedule the replacement of the bulbs annually to ensure the system's efficiency. These high-quality lamps have a peak UV output of 254nm that help in reacting with the genetics of microorganisms such as spores, virus, bacteria, and other pathogens.
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.
