The plug and outlet are typically not designed to interrupt an electrical circuit. There maybe arcing which could lead to damage of the outlet that could eventually lead to a fire hazard. It’s best to have a habit of using a switch to shut off the light or any appliance prior to unplugging it.
Can fluorescent ballast cause fire?
Overheated fluorescent lights can cause fires! Overheating of the ballast could result in the following: Ignition of nearby combustible materials. Explosion of the ballast due to the generation of gases inside.
Can a ballast catch fire?
An overheating ballast can become hot enough to ignite combustible ceiling tiles or any other combustible it contacts. Check behind the fixture for fire extension. Ballasts contain a transformer and a small capacitor.
Do ballasts draw power?
Newer electronic ballasts don’t draw energy unless a load is present.
What are the common problems of fluorescent lamp?
defective starters, defective bulbs or a defective ballast. IMPORTANT: Flickering fluorescent tubes can cause the ballast to overheat and fail prematurely! They can even cause a starter to burn out! Don’t wait too long to fix the problem or you may end up with a bigger repair!
Are fluorescent light bulbs a fire hazard?
A CFL uses electricity to heat an element in the lamp’s base that excites the mercury vapor gas in the coils so that they emit light. When a CFL can no longer produce light, the electronics in its base will still try to function, sometimes leading to overheating, smoke and fire.
What causes ballast to burn?
Every ballast has an ambient operating temperature range and UL location rating. 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 and ballast failure.
How do I know if a ballast is bad?
If your fluorescent lighting is displaying any of the signs below, it could be a symptom of a bad ballast:
- Flickering. …
- Buzzing. …

What is the simplest problem that can be diagnosed in fluorescent lamp?
Single Pinned Lamps
This problem arises when one of the fluorescent light lamp pins is missing in the socket or poorly connected to the socket. This is an easy fix and does not require calling a professional. You just need to remove the lamp from the socket and reinstall it.
Does my fluorescent light have a starter?
Not all fluorescent lights have starters, but if yours does, it will usually be located near a tube socket. Lights with more than one tube have a separate starter for each.
How do you bypass a fluorescent starter?
On the surface, performing a ballast bypass seems simple:
- Turn Off the Mains Power. …
- Locate The Ballast On The fluorescent Light Fixture. …
- Cut The Hot And Neutral wires. …
- Cut Socket Wires. …
- Remove The Ballast. …
- Reconnect The Wires.
What will happen if the starter is removed while the tube is glowing?
Without the starter, a steady stream of electrons is never created between the two filaments, and the lamp flickers. Without the ballast, the arc is a short circuit between the filaments, and this short circuit contains a lot of current. The current either vaporizes the filaments or causes the bulb to explode.
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.
How do you know if a fluorescent tube is blown?
Quote from the video:
Quote from Youtube video: The most likely cause of a blown tube is the filament is burnt. Off. So that's what we're going to test using a multimeter. We're going to turn on our meter and set it to the album setting.

How do I know if my ballast 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 happens if you put a T8 bulb in a T12 fixture?
T12 vs T8 Fluorescent Tubes
T12 tubes are 1.5″ in diameter while T8s are just one inch. All other things—socket sizes, lengths, distance between pins—are the same. T8 LED tubes won’t fall out if you try to install them in a T12 fixture—they’ll fit just fine.
