Do UV lights need a ballast?
Medium pressure UV lamps do not have a filament. They utilize a high voltage charge to ionize a mercury/gas mixture in the lamp creating a plasma that emits UV light. This system requires a high voltage/amperage power supply (typically a magnetic ballast transformer with a high voltage capacitor bank).
What is a UV power supply?
A power supply system consisting of a single-phase (208 to 240 volts) supply, which including the choke and igniter. It will efficiently operate UV curing lamps of up to 150 V.
Do UV lamps need replacing?
UV lamps should be replaced once every 12 months. UV lamps have a lifespan of approximately 9,000 hours. After the UV lamp burns out, you are quite simply passing water through a tube of glass inside a pipe. Whenever you are replacing your UV lamp, it’s also important to replace the UV system’s o-rings as well.
What dries with UV light?
UV light is used to cure concrete, vinyl, and tiles to improve stain resistance and increase the durability of the flooring product. This process is extremely effective with no toxic odor from chemical treatment, and allows for immediate occupation making it possible to walk on the floor within minutes of treating.
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.
What is a UV light 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.
How many amps does a UV light use?
11 X 14 8 – 1″ diameter tubes 120 VAC – 2.2 Amps – 265 Watts 11 X 14 HO 8 – 1″ diameter tubes 120 VAC – 3.3 Amps – 400 Watts 14 X 16 12 – 1″ diameter tubes 120 VAC – 3.3 Amps – 400 Watts 14 X 16 HO 12 – 1″ diameter tubes 120 VAC – 4.5 Amps – 540 Watts 18 X 20 12 – 1½” diameter tubes 120 VAC – 3.3 Amps – 400 Watts 18 X …
Do UV lights lose their strength?
Like your average light bulb, UV lights have a finite life span that requires them to be changed on a regular basis. As these lights operate, they slowly lose their effectiveness as a germicidal agent by about 15 percent each year.
Do UV bulbs expire?
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. After the first year, all UV lamps by their fundamental design will have lost nearly half of their germicidal effectiveness.
Can you put metal in a UV lamp?
Metals are almost entirely unaffected by UV because of the availability of free electrons to absorb photon energy without undergoing energy transitions or bond dissociation.
Why does my UV bulb keep blowing?
If your UV Sterilizer is blowing filaments, I suggest cleaning the UV very carefully and inspecting for moisture. If no moisture is found, likely your electronic ballast has shorted as this will also result in a blown filament (moisture causes a temporary short).
