Are ballast supposed to get hot?
Ballasts usually run hot, about 140 degrees F, but if one is so hot that you can’t keep your hands on it, it is likely the culprit.
Do magnetic ballasts get hot?
Heat can be a problem with magnetic ballasts, and you’ll find that they can be quite hot to touch after running. As well as this, they will run with a slight humming sound, thanks to the inside components. This can get louder over time and use as they wear down.
How long should ballasts last?
12 to 15 years
According to the Certified Ballast Manufacturers Association, the average magnetic ballast lasts about 75,000 hours, or 12 to 15 years with normal use. The optimum economic life of a fluorescent lighting system with magnetic ballasts is usually about 15 years.
Do digital ballasts wear out?
For optimum efficiency, you should replace your magnetic ballast every 2-3 years. Digital ballasts last much longer, and have a consistent output over their life. They only need replacing if they stop working, which can be 10+ years.
Why is my ballast overheating?
Any issue that causes excess voltage to run through the fluorescent bulb ballast leads to overheating, and incorrect wiring during the construction of the fixture or installation is one of the most common causes of this problem.
Can a ballast catch fire?
Overheated fluorescent lights can cause fires! Overheating of the ballast could result in the following: Ignition of nearby combustible materials. Explosion of the ballast due to the generation of gases inside.
What’s the difference between digital ballast and electronic ballast?
Digital ballasts have higher output and will give almost 30% more light. They are cooler and provide better spectral output. They have adjustable wattage, which allows you to use power your grow lamp at different wattages.
What causes ballast to burn?
Every ballast has an ambient operating temperature range and UL location rating. When it’s too hot or too cold, the ballast can burn or fail to start your lamps at all. Heat combined with prolonged condensation inside an electronic ballast can cause corrosion and ballast failure.
How much power does an electronic ballast use?
about 13 to 16 watts
Electronic Ballasts On a typical fixture with two 4 foot 40 watt T-12 fluorescent lamps, the ballast consumes about 13 to 16 watts of electricity. Thus the total consumption of the two lamps plus the ballast is about 93 to 96 watts. The most efficient ballasts are electronic, or high-frequency ballasts.
Can a bad ballast cause a fire?
As with any electrical situation where overheating is possible, a bad ballast can pose a fire danger. The overheated ballast could cause the plastic housing on the light itself to melt and, in the right conditions, flame up.
