What is a Type P 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.
How do I know what size ballast I need?
By selecting a ballast with an ideal ballast factor, you can optimize the light output of your fluorescent lighting system and maximize your energy savings. To estimate your total system lumens, multiply the rated lumens of your lamp by the ballast factor. For example, 3200 lumens x 0.77 BF = 2464 total system lumens.
Why do you need a ballast for a fluorescent light?
Using more sophisticated circuitry and components, ballasts can control the current running through fluorescent lights with greater precision. Compared to their magnetic counterparts, they’re smaller, lighter, more efficient and—by supplying power at a much higher frequency—less likely to cause flickering or buzzing sounds.
How to remove the ballast from a light fixture?
How to 1 Turn off power to the fixture 2 Open fixture and remove the bulb and ballast casing 3 Using the wire cutters, cut both power (brown) and neutral (blue) wires coming into the fixture 4 Cap the wires with wire nuts. 5 Use the wire cutters to cut the wires connected to the sockets. 6 Remove the magnetic ballast
What kind of ballast is needed for switch start?
Switch start is the control gear that has been used by the industry for years. They are general considered old technology and less manufacturers are creating them. Switch start requires a wire wound magnet choke of ballast.
What kind of meter do you use to test a ballast?
Testing a ballast with a multimeter/volt-ohm meter In order to ensure that the issue is with the ballast, you will want to test it with a multimeter. A multimeter is designed to measure electric current, voltage and resistance. They are inexpensive and can be found at most electronics shop.
