Do fluorescent lights have a fuse?

Fluorescent light bulbs are commonly used in photographic light and kitchen light fixtures. A fuse is the first place to check when a fluorescent light fixture will not light up after the switch is turned on. When the fuse is blown, electricity cannot flow from the power source into the lamps inside of the bulb.

Why is my tube light not working?

If a fluorescent tube neither lights nor flickers when switched on, first check to see that the fixture is plugged in and that no fuse has blown or circuit breaker has tripped. If this does not help, try wiggling the tube gently in its sockets by rocking it back and forth and from side to side.

What causes fluorescent lights to not come on?

The fluorescent tube won't turn on

No electrical power due to a tripped breaker or blown fuse. A dead or dying ballast. A dead starter. A dead bulb.

Where is the fuse in a fluorescent light?

Remove the bulbs by twisting them out of their holder to see if the fuse is mounted underneath them. The fuse is a small metal cylindrical-shaped device mounted inside the light fixture.

Can you touch fluorescent tubes?

YES! You should not touch halogen capsule bulbs with your fingers. Halogen bulbs, tubes and capsules are made of quartz, rather than ordinary glass, so they can withstand the higher temperatures.

Do fluorescent ballasts have fuses?

The fluorescent ballasts have the fuses on the side of the ballast, and you can see it without opening the ballast.

How do you check a tube light?

Test the electrodes using a multimeter.

If the electrodes are not intact, the bulb will not have a current running through it. Place the probes on both pins of the tube light to get an accurate reading. If there is no reading on the multimeter, the bulbs should be replaced.

How do I know if its the ballast or bulb?

One probe of the multimeter should touch the hot wire connections, while the other touches the neutral wire connections. If the ballast is good, an analog multimeter has a needle that will sweep to the right across the measuring scale. If the ballast is bad, then the needle won't move.

How do you test a fluorescent light fixture?

Set a multimeter to the ohm (Omega symbol) setting, then touch one tester probe to each of the pins at the end of the bulb. If the tester shows a reading between 0.5 and 1.2 ohms, the bulb has continuity. Repeat the test at the other end of the bulb.

What are the main causes of not starting tube light after switch on?

When a starter is old and worn, there may be insufficient discharge current through the tube to keep the gas ionized, which can result in 'blinking' at the ends of the tube, as the starter filament is brought in and out of operation.

How do you fix a light that won't turn on?

Tighten the bulb if it is loose, then try the switch again. If a problem remains, be sure the switch is off, remove the bulb and substitute a new one. If the light does not work with a new bulb, check whether the circuit breaker or fuse governing the fixture has tripped or blown.
