It is also called a starter because of its action. supports HTML5 video. If necessary, replace the ballast and the cover. If your An electronic ballast is a device which is used to limit the current of a load such as tube light or fluorescent lamps. An electrical ballast is a device placed in series with a load to limit the amount of current in an electrical circuit.. A familiar and widely used example is the inductive ballast used in fluorescent lamps to limit the current through the tube, which would otherwise rise to a destructive level due to the negative differential resistance of the tube's voltage-current characteristic. A fluorescent electronic ballast is a device that helps fluorescent lighting fixtures glow. Place your fluorescent lamp somewhere safe, for they are too fragile. A further test would be to check for heat from the ballast. If you've been hearing this, you need to test the ballast. your digital multimeter’s probes to the white and black wire. Usually used in indoor lighting, most NOAA Hurricane Forecast Maps Are Often Misinterpreted — Here's How to Read Them. If your fluorescent lighting starts to act like HID when you turn it on, and it's slow to reach full brightness (what lighting experts call illuminance), your ballast is most likely the culprit. If your fluorescent fixture is not working properly, use a multimeter, also called a volt ohm meter, to check the fixture's voltage to determine if the problem is the ballast or another … All it takes is one flicker for the panic to set in.

Ballast that is working will read a continuous circuit. Without a ballast to control this, there would be too much current for the light to take, and it would burn out and possibly even catch fire. Put one of the multimeter's probes into the wire that is connecting the white wires together, and then place the remaining probes in contact with blue, yellow and red wires leading away from the ballast; not all ballasts will have a yellow wire. Amazon and the Amazon logo are trademarks of Amazon.com, Inc or its affiliates. Thank you all! A ballast can only slow down changes in current -- it can't stop them. For Ballast that’s not working correctly, a replacement should be done. You could set up a test rig for tubes, but it would be little more than a fluorescent light fixture on a bench. If your fluorescent light is experiencing luminance (a state where your fluorescent light is slow to reach full brightness), then its electronic blast has a problem. Steps to follow when testing your electronic Ballast, ​Electronic ballasts are quiet and do not flicker, ​They are smaller and weigh lesser than the magnetic Ballast. The repair will only take about 10 minutes. After this, the multimeter’s meter should be reading direct short. When your fluorescent light flickers or makes a loud and annoying hum, a degrading ballast is the cause. Fluorescent bulbs use a gas and electricity to create illumination, while a regular bulb uses heat, which costs more to power.
