What is a Class P type ballast?

What is a Class P type ballast?

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 are the two types of ballast?

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.

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.

How do you know if ballast is bad?

If your fluorescent lighting is displaying any of the signs below, it could be a symptom of a bad ballast:

1. Flickering.
2. Buzzing.
3. Delayed start.
4. Low output.
5. Inconsistent lighting levels.
6. Switch to an electronic ballast, keep lamp.
7. Switch to an electronic ballast, switch to a T8 fluorescent.

How do I know if I have a T8 or T12 ballast?

If no markings are available, the size in diameter of the tube is the easiest way to determine the type you have installed. T8 tubes are 1-inch in diameter and T12 tubes are 1 1/2 -inch.

What causes a ballast to fail?

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.

Can I use any ballast?

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.
