What are the two types of ballasts?
Once the arc is established, the ballast regulates the energy going into the bulb to help increase the bulbs efficiency, longevity and light output. There are two categories of ballasts – magnetic and electronic. Magnetic ballasts are the most basic type and operate bulbs through a core and coil transformer.
What are the two types of ballast used in fluorescent lighting?
There are two lamp families that work with a ballast: fluorescent and HID. And there are two types of ballasts in each family: magnetic and electronic. Magnetic ballasts are the older ballast technology. For the fluorescent family, both T12 linear fluorescents and two-pin CFLs use magnetic ballasts.
How do I know which ballast to use?
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.
What is a ballast in lighting?
ballast – A device required by electric-discharge light sources such as fluorescent or HID lamps to regulate voltage and current supplied to the lamp during start and throughout operation.
Are all ballast the same?
When considering a ballast for your lamp, make sure they have corresponding ANSI (American National Standards Institute) codes. Matching ANSI codes guarantees that the ballast you chose can be used with your lamp. However, ballasts are often compatible with more than one lamp, and vice versa.
What is inside a ballast?
A magnetic ballast (also called a choke) contains a coil of copper wire. The magnetic field produced by the wire traps most of the current so only the right amount gets through to the fluorescent light. That amount can fluctuate depending on the thickness and length of the copper wire.
What’s the difference between T8 and T12 ballast?
T12 and T8 lamps also differ on the ballast that they are operated with most of the time. T12 primarily run off a magnetic ballasts and T8 bulbs operate on electronic ballasts. Most commercial buildings and people that use them in their homes have the instant start ballast that operates the T8 light bulb.
Can I use any ballast?
What are the different types of ballasts?
There are several different kinds of ballasts, but the three basic types are electronic ballasts, magnetic ballasts and digital.
What is the purpose of a ballast?
Ballast is a granular material which is placed and packed below and around the railway sleepers. Different types of ballast materials used are broken stone, sand, gravel, moorum, brickbats etc. The main purpose of ballast is to transmit the load from sleepers to the formation(consolidated track bed) and to provide drainage facilities to the track.
Ballast is any substance that is used in ships or hot-air balloons to make them heavier and more stable. Ballast usually consists of water, sand, or iron.
What is a trigger start ballast?
Trigger start is another magnetic ballast technology that is also used with preheat lamps. Trigger start ballast additionally provide a low voltage filament heat to improve lamp life.
