Fluorescent Light Problems and Repair
Determine whether the starter needs to be replaced by considering the manner in which the light works. If the light fails to work at all, the problem is likely to be with a broken or blown bulb and it will need to be replaced. However, if the light flickers, works intermittently or takes a long time to illuminate, then the issue is caused by the fluorescent starter and it will need to be replaced.
How does a fluorescent starter work?
When you turn on a fluorescent tube, the starter is a closed switch. The filaments at the ends of the tube are heated by electricity, and they create a cloud of electrons inside the tube. The fluorescent starter is a time-delay switch that opens after a second or two. When it opens, the voltage across the tube allows a stream of electrons to flow across the tube and ionize the mercury vapor.
Easy fixes for slow to start, flickering or faulty fluorescent tubes
If you are experiencing any of the following problems with your fluorescent tubes then this page will tell you how to fix them, including information on what has likely caused the problem and how to check your starters and ballasts:
I always keep a spare starter. Sometimes the starter contacts corrode and a simple couple of twists of the starter gets things working. The lamps usually last for yonks but if you can see black residue at the ends-inside the tube then it probably is naff.
Fluorescent Lights Complex, But Problems Easy To Fix
As a result, simply replacing the bulb-actually a tube-when a fluorescent light develops problems will not always remedy the situation. Fortunately, trouble-shooting fluorescent lights is not too difficult, and repairs are usually easy to make.
How to Replace a Fluorescent Tube With an ETL Approved LED Tube
Instructions. 1. Switch off the power to make sure no risk of the electric shock. 2. Remove the applicable diffuser or cover, and take the fluorescent tube from the fixture.
How to Fix a Fluorescent Light
An old tube blinks off and on just before it dies; repairs are often simply a matter of replacing it. This problem may also occur because of poor contact between the pins at the ends of a tube and the tube holders. If the pins are bent, use needle-nose pliers to straighten them. Clean the pins and socket contacts with fine sandpaper.

Sainsbury’s was an early adopter of LED lighting. The supermarket giant has been looking into LED technology for about seven years, first for refrigerator lighting, and later feature lighting and car parks. Over time, as the technology got more powerful, it spread to more applications.
