Do UV lights need a 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.
How long should a UV ballast last?
According to the Certified Ballast Manufacturers Association, the average Magnetic ballast lasts about 75,000 hours or 12 to 15 years with regular use. In contrast, the Electronic ballast can last up to 20 years.
How long does UV light ballast last?
between 50,000 and 75,000 hours
How long do ballasts for UV light fixtures last? Just like a light bulb, electronic ballasts for germicidal UV has a specific life span. Usually this is represented in a number of hours, since the amount of time using light bulbs will vary. A standard number is usually between 50,000 and 75,000 hours.
How do you know if your UV ballast is bad?
If your fluorescent lighting is displaying any of the signs below, it could be a symptom of a bad ballast:
- Flickering.
- Buzzing.
- Delayed start.
- Low output.
- Inconsistent lighting levels.
- Switch to an electronic ballast, keep lamp.
- Switch to an electronic ballast, switch to a T8 fluorescent.
How does a UV light ballast work?
The ballast is wired in series with the lamp and performs two functions. Initially, the ballast provides a high voltage charge to ‘strike’ or ‘ionize’ the mercury. Then, once the mercury is ionized, the ballast reduces the voltage and amperage required to keep the mercury ionized and emit a stable stream of UV light.
Are UV lights for AC worth it?
Direct exposure to the UV-C used in HVAC systems is hazardous, particularly to the skin and eyes. With the right conditions and proper installation, UV lights can be very effective at killing viruses, mold, and bacteria. The two working together can make your home or office building a much healthier place.
How often should UV bulbs be changed?
approximately every 12 months
Typically, a UV lamp being used primarily to disinfect the air circulating through a home or small office should be replaced every 9000 hours or approximately every 12 months.
