Fluorescent Lights

Question or Comment?

Fluorescent lights contain a gas that produces invisible ultraviolet light (UV) when the gas is excited by electricity. The UV light hits the white (phosphorus) coating inside the bulb and produces light.

Incandescent bulbs are connected directly to line voltage through a light fixture. Fluorescent bulbs use a ballast which transforms line voltage to the special type of voltage to start up and operate the bulb(s).

Turning a fluorescent bulb on and off frequently can shorten the life of a bulb. New fluorescent bulbs may be whiter and brighter than an old bulb.

How to Dispose of Fluorescent Lights

Fluorescent bulbs contain a small amount of mercury and are considered household hazardous waste. Most states allow households to place compact fluorescent lights (CFLs) in the trash.

Recycling is a much better option for the environment. It is convenient to drop off used CFLs at certain home improvement stores. Fluorescent lights can be dropped off at community recycling events, or a hazardous waste collection center. They can also be dropped off at Batteries Plus for a fee.

Fluorescent tubes should not be disposed of in the trash. Home improvement stores normally accept only CFLs for recycling. However, if you call the electrical department of your local home improvement store, ask if you can drop off these tubes, they may accept them. Otherwise see for fluorescent tube recycling locations.

How to Clean Up Broken Fluorescent Bulbs

Be very careful when handling fluorescent bulbs. Here are two sets of recommendations from the EPA for cleaning up a broken CFL.
