Fluorescent (tube) lighting is more efficient than incandescent (bulb) lighting, so it's popular in areas where you need lots of light, but don't want a big electric bill. That includes places like the kitchen and garage or workshop. Because they are simple in operation, fluorescent lighting systems are also easy to fix. Here's what you need to know.

Fluorescent lighting typically is easy to work on with the exception of smaller units that may not allow access to internal parts. If the bulb is okay, but the unit still doesn't work, check the electrical cord and replace the unit as needed.

How Does It Work?

A fluorescent lighting fixture converts electricity into light by making gas inside a phosphor-lined tube glow. The fluorescent fixture is either wired into the house electrical system or plugged into a nearby receptacle. Electrical voltage is delivered to the fluorescent tube by a component called the ballast. When the fixture is turned on, more electricity is needed than during normal operation, so a starter tells the ballast to boost the voltage. Once running, the starter turns off and the ballast maintains the voltage to a lower operating level.

What Can Go Wrong?

Any of the main components of a fluorescent lighting fixture can be the source of problems. That includes fluorescent tubes, starters, ballasts, and switches. Problems with fluorescent lighting systems are relatively easy to diagnose and solve.

Caution!

Be especially careful when handling fluorescent lighting tubes. They are quite fragile and contain phosphor and inert gasses. Don't drop them or let them hit a hard surface!
