A compact fluorescent light bulb (CFL) uses about 75 percent less energy than an incandescent light bulb.  It lasts about 10 times longer than an incandescent bulb and will save about $30 over its lifetime, paying for itself in about 6 months.

Fluorescent lighting works differently than incandescent lighting.  In an incandescent light bulb the electricity runs through a wire filament heating the filament until it begins to glow.  In a compact fluorescent bulb electricity moves through a tube containing argon and a small amount of mercury vapor which causes an invisible ultraviolet light that triggers the fluorescent coating, phosphor, into the tube’s interior which finally emits a visible light.

Fluorescent bulbs use a little bit more energy when they are initially turned on but once the electricity begins to course through the bulb it uses significantly less energy than an incandescent bulb.

Fluorescent lighting tips:

Look for CFL bulbs that are rated with the Energy Star label.  These bulbs meet the minimum performance requirements.  They will perform better and they will not make the buzzing sound that some of the original CFL bulbs made.

Your CFLs will last longer if you leave them on for at least 15 minutes or more each time you flip the switch on.

It takes a little while for the bulb to reach its full brightness.  If it does not turn on immediately when the light is switched it does not indicate a defect.

Use the bulbs where they are designed to be used.  Do not use regular CFL bulbs with dimmable switches or in 3-way sockets.

Be careful of the temperature in which the CFL bulb is being used.  If you use the bulb outdoors be sure that it is protected from the elements.  When CFLs are exposed to overly hot conditions they will have a shorter lifespan.

Because Compact Fluorescent lights contain small amounts of mercury they need to be disposed of properly.  Many chain stores such as Home Depot and Lowes will offer CFL recycling programs.
