What are the two types of ballasts?
What are the two types of ballasts?
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. For HIDs, some metal halides and HPS lamps use magnetic ballasts.
What is a triad ballast?

What do the numbers mean on a ballast?
About Advance Ballasts and Fluorescent Lamps. Advance Ballasts that utilize fluorescent lamps usually come in two shapes, straight and u-shaped. Most fluorescent types are T5, T8, and T12. The T stands for tubular and the number provides the diameter in 1/8 of an inch. Therefore, a T12 ballast must use a T12 bulb.
What does class P ballast mean?
Class P: A ballast for a fluorescent lamp which meets the requirements of the Underwriters’ Laboratories, Inc.; includes an automatic resetting thermal protector to remove the ballast from the circuit if its temperature exceeds a specified value. 4. Same as constant-wattage ballast.
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.
Can you wire a ballast wrong?
Replacement ballast should always match in voltage, wattage and brand. Wrong ballast types can cause fires or shorts.
What does a ballast do?
In a fluorescent lighting system, the ballast regulates the current to the lamps and provides sufficient voltage to start the lamps. Without a ballast to limit its current, a fluorescent lamp connected directly to a high voltage power source would rapidly and uncontrollably increase its current draw.
Why do ballast go bad?
Causes of Ballast Failure Premature ballast failure is often caused by the surrounding environment. 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.
What is a ballast used for?
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.
