How can you tell the difference between magnetic and electronic ballast?
Similarly, can I replace a magnetic ballast with an electronic one?
Older fluorescent light fixtures utilized a magnetic ballast to control the flow of electricity through the light bulbs. If you have an older fixture, you can switch from a magnetic ballast to an electronic ballast in a few minutes with some basic hand tools.
Similarly, what is a preheat magnetic ballast? Preheat start is a magnetic ballast technology that is used exclusively with preheat start lamps. Starting voltage for the lamp is about 600V for a 4 ft T8 lamp. This method maximizes energy savings but decreases lamp life due to the reduction in the life of the electrodes (10,000 to 15,000 on/off switching cycles).
Also Know, how do I know which ballast to get?
You can determine whether you have a compatible fixture in seconds. Simply turn the light on, then take a photo of the fixture using your smartphone or digital camera. If there are no dark bands on the resulting image, you have an electronic ballast that will work with direct drop-in LED tubes.
How long do electronic ballasts last?
about 20 years
