Turn off the power, remove the bulbs, and remove the cover to expose the ballast. If you see tar leaking from the ballast it is bad and must be replaced. If you see no tar then proceed. Use a multimeter to check for continuity. The yellow and blue wires are the power wires and the white wire is neutral. With the meter set to ohms check between the yellow wire and white wire at the end where it connects to the light. If you get no reading the ballast is bad. Now check the other side where power is coming in. No reading and the ballast is bad. If you get a reading at both ends it is good. Check for loose wires.
true
Clean ballast refers to the ballast stored in a tank not permanently utilized for ballast (see segregated ballast below), but has been cleaned prior to use so clean ballast stored in it, if discharged from a stationary ship into calm water on a clear day will produce no evidence of oil, sludge or emulsion on or under the surface of the water or on adjoining shorelines. Segregated ballast refers to ballast stored in tanks which are permanently utilized for the carriage of ballast, and are completely separated from the cargo oil and oil fuel system.
Daylight Fluorescent lamps have bluish-white illuminance, whereas coolwhite fluorescent lamps have yellowish-white illuminance.
No.
For most purposes fluorescent is better; they convert a greater percentage of electricity to light, and thus have less losses.
A pin based fluorescent light fixture is the type of fixture that takes fluorescent tubes. On each end of the fluorescent tubes there are contact pins. These pins are used to hold the tube in the fixture and to supply the voltage to the tube from the fixture's ballast.
Depends if ballast is in fixture and switch is on. Several watts if new ballast and perhaps 15 watts for old ballasts....
No, the ballast's output is not matched to operate a fluorescent bulb.
Yes
Yes, there is an excitation current that flows through the primary side of the transformer which is located in the magnetic ballast's casing.
The voltage of your area is what determines the operating voltage of all equipment. Equipment from other countries usually has to use a transformer to get the correct voltage. The voltage on a fluorescent fixture is printed on the ballast of the fixture. See if the voltage on the ballast matches the supply voltage of the system that you are going to use to operate the fixture.
The voltage present on the secondary side of the ballast (transformer) varies as to the type of fluorescent tube or bulb that is in the fixture. The voltage will always be higher that the applied line voltage that supplies the ballast.If the fluorescent bulb screws into a lamp type of fixture, then there is no way to measure the voltage at the bulb as the tube and ballast are a combined sealed unit.
For information about fluorescent tube lights see the answers to the Related questions and the Related link shown below.
The terminology T8 suggests to me that the fixture is a fluorescent fixture. These types of tube fixtures need a ballast to make the tubes ignite. If you are trying to operate this type of fixture on 220 volts, you will need a ballast that requires a 240 volts input voltage source.
It is possible, depending on the ballast wiring to the tubes. Some ballast units actually contain multiple independent ballasts that would be hooked to individual tubes or pairs of tubes independently. Some ballasts may control all the tubes in one fixture and when one tube fails the others either go out or flicker badly.
Look on the ballast inside of the fixture. There is an amperage and a voltage on the ballast label. Use this equation to find the wattage. W = I x E, Watts = Amps x Volts. This will give you the answer that you are looking for.
If the fluorescent tubes work in a different fixture then the ballast may be defective.
