Frequently Asked Questions (FAQs)
1. How can you tell if a UV bulb is good?
If it turns a violet shade, the UV light bulb is functioning. If it remains primarily white, the UV light bulb might be defective. If you are unsure, transfer the bulb to another light fixture and try the same test again. If it still fails, the light bulb is not good.
2. How long do UV filter bulbs last?
How long will a UV lamp last for? Typically 9,000 hours or 1 year. After this, the UV lamp will still be on (you can still see the blue light) but it won't give out an appropriate UV dose. Some UV lamps using newer technology will last for 2 years now.
3. Do UV light need ballast?
The uvc light ballast ramps up the input voltage and has an output voltage high enough to spark the lamp. A ballast is needed due to the construction of the lamps, they have negative resistance between the two electrodes. Additionally, a large voltage difference between the electrodes is needed to spark the lamp.
