Causes of Ballast Failure
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. Some people may suggest removing the parts of the ballast casing and cleaning the electrical board.

Likewise, does a ballast store electricity?

An electrical ballast is a device that limits the current through an electrical load. These are most often used when a load (such as an arc discharge) has its terminal voltage decline when current through the load increases. Series resistors are used as ballasts to control the current through LEDs.

Also Know, how do you bypass a ballast? Cut the socket lead wires. The socket lead wires (most likely red and blue-colored wires) are located on the other side of the ballast and connect to wires going out of the ballast to the sockets (which should be non-shunted sockets for T8 LEDs). These output wires provide the power to the lamps.

Likewise, people ask, how do you fix a fluorescent light fixture?


  1. Turn off power at circuit-breaker box.
  2. Remove lens or diffuser panel from light.
  3. Remove lamps or bulbs.
  4. Remove ballast cover.
  5. Uncap black and white wires and test to ensure that power is off.
  6. Separate wires from existing fixture.
  7. Remove fixture base from ceiling.

How do I know if I have a t8 or t12 ballast?

This will reveal a lot about your current fluorescent tube and usually indicate if the bulb is T8 or T12. 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 is the purpose of a ballast?

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.

What should you use to check the voltage in the ballast?

CHECKING THE STARTING VOLTAGE OF A SLIMLINE BALLAST SHOULD ONLY BE PERFORMED BY A LICENSED ELECTRICIAN. The starting voltage is measured across the primary and secondary leads to the sockets, using a high resistance voltmeter with a range of zero to 1000 volts.

What are ballasts made of?

They're usually rectangular black boxes with wires coming out of one or both ends. Lighting ballasts for fluorescent light bulbs and HID lamps made before 1980 may contain polychlorinated biphenyls (PCBs).

How does a ballast work on a boat?

Ballast is material that is used to provide stability to a vehicle or structure. A compartment within a boat, ship, submarine, or other floating structure that holds water is called a ballast tank. Water should move in and out from the ballast tank to balance the ship.

How long have fluorescent lights been around?

Albert W. Hull of GE's Schenectady Research Laboratory filed for a patent on this invention in 1927, which was issued in 1931. General Electric used its control of the patents to prevent competition with its incandescent lights and probably delayed the introduction of fluorescent lighting by 20 years.

How do you test a light socket?

  1. Turn the power off to the socket.
  2. Test the socket by attaching the clip of the continuity tester to the hot screw terminal, the black wire lead. Then, touch the probe to the metal tab in the bottom of the socket.
  3. The tester should glow. If it doesn't, the socket is faulty and needs to be replaced.

Why does my fluorescent light go on and off?

If a fluorescent tube blinks on and off-a slower and more distinct process than flickering-the fault may lie in loose wiring or in another component, called the ballast. The ballast is almost always to blame if the fixture hums during operation.

Do LED lights flicker?

There's no flickering. LED bulbs don't have glowing filaments. When the dimmer switch goes off and on many times per second, the LED bulb becomes a flickering strobe light. In rare cases, the flickering can be some other power supply issue, which may be the explanation if you don't have dimmer switches.

Are flickering fluorescent lights dangerous?

Fluorescent lamps with magnetic ballasts flicker at a normally unnoticeable frequency of 50 or 60 Hz. This flickering can cause problems for some individuals with light sensitivity and are associated with headaches and eyestrain.

Where can I donate fluorescent lights?

Take lamps and tubes to a household hazardous waste collection center or event. Find where to recycle or dispose fluorescent lamps and tubes at Where Can I Recycle My?, or Earth 911, or call 800 CLEAN-UP (253-2687). Enter your zip code to find the nearest recycling center.

Will a t8 bulb work in a t12 fixture?

T8 tubes are simply 1 inch in diameter versus the 1.5 inch diameter of T12 tubes. In an effort to make LED tube lights compatible with the internal dimensions of most fixtures, you will find that most LED tube lights feature a T8 or 1 inch diameter. They can indeed be used in T12 fixtures.

What does HID stand for?

High-intensity discharge lamps

Why do they add weight to touring cars?

Ballast weight is something that is added to a race car to alter its performance. In some racing series, for example the British Touring Car Championship, ballast is used as a handicap, the leading drivers at the end of one race being given more ballast for the next race.
