How long should UV ballast last?

Usually UV lamp life is from 9000 to 12000 hours depending on different brands, normally using one year you need to replace the Germicidal lamp because the UV output dose will get weaker and weaker and affect the sterilization effect. So how about UV light ballast? How long should I replace them?

The answer is UV ballast lifespan is much longer then UV lamp,no need to replace every year.Usually Mid-end ballasts can be used for 3-5 years when the parameters of the electronic ballast are completely matched with the UV lamps. High-end ballasts typically have a lifespan of 5-10 years.

The design service life of Haisen UV ballast is generally 10 years, many our customers use our ballasts more than 10 years and still serve well.
