4 Pin on a Single End - 22 Watt Germicidal Water Treatment Bulb
The Neptune WTA 05-0294-1 Replacement UVC Light Bulb is a four pin on a single end 22 Watt germicidal water treatment bulb that has a total length of 17.72" and an arc length of 14.57".
This UV-C bulb is made out of ceramic and is capable of protecting you from waterborne bacteria, molds, viruses and other pathogenic microorganisms such as giardia and cryptosporidium. This method is known to be a cost effective way of protecting water from contaminants. With the intensity of 253.7 nm, the UV light emitted by the light bulb kills DNA and other microorganisms in water. When water is exposed to a UV light source it renders the microbes and bacteria present in water sterile. Researchers are of the opinion that UV rays are effective to destroy 99.99% germs in water that may possibly cause harmful bacteria and microorganismss such as organisms causing gastroenteritis, typhoid, influenza virus, Vibrio cholerae, and hepatitis virus strains. Since UV filters do not introduce chemicals into the water and is a purely physical state, it is a far better option to chlorination and its by-products. Experts are of the opinion that it is better to replace the UV light bulb annually though it may continue to emit light for efficiency.

QUESTIONS & ANSWERSAsk a Question
Where are these bulbs manufactured?
We have UVC bulbs from China and from the US. If you need a particular country of origin, please let us know and it's likely we can accomodate your request. Sometimes this affects the price but other times it does not. I believe this particular bulb in stock is from China so a US made one may take a few extra days.
