Compact Fluorescent Light (CFLs) is miniature fluorescent lights that contain the starting ballast in the base of the bulb. CFLs are a much more efficient way to create light than the incandescent lights we have used for so many years; they save money and help the environment.
CFLs use about 75% less electricity for the equivalent amount of light and last up to 10 times as long. They also produce about 75% less heat so they are safer to operate. A 60 watt equivalent CFL can save you $40 or more and reduce greenhouse gas emissions by at least ¼ tonne over its life time.
The average household has more than 30 light bulbs …. Add up your potential savings and the benefits to the environment.
How to choose and where to use CFLs:
CFLs provide the greatest savings in fixtures that are on for a substantial amount of time each day. At a minimum consider installing CFLs in fixtures that are used at least 15 minuets at a time or several hours per day. Installing CFLs in fixtures that are turned on and off frequently will shorten the lifespan of the bulb, therefore they should not be used in conjunction with motion sensors.
How to choose the right light:
Matching the right CFL to the right kind of fixture helps ensure that it will perform properly and last a long time, for example:
- CLFs perform best in open fixtures that allow airflow, such as table or floor lamps, wall sconces, pendants and outdoor fixtures.
- For recessed fixtures, it is better to use a reflector CFL than a spiral one since the design of the reflector evenly distributes the light down to your task area.
- If the light fixture is connected to a dimmer or three way socket fixture, you’ll need to use a special CFL designed to work in these applications. Make sure to look for CFLs that specify use with dimmers or three-way fixtures.
- Choose a CFL that offers a shade of white light that works for you. CFLs come in a range of light color and quality from a warm reddish or yellow to a cool bluish tone.
- CFLs are rated as “equivalents” to incandescent lights based on the brightness of the light they produce as measured in ‘Lumens” .Consult the following chart to determine what CFL wattage is best to replace your incandescent light bulb.
- Most CFL packaging will include terms such as “ Soft White 60” or “60 Watt Replacement”

CLF Disposal
CFLs contain a small amount of mercury, less than a watch battery, and should be disposed of in an environmentally friendly manner, and clean up broken bulbs with care.
If a CFL breaks sweep up, don’t vacuum, all glass fragments and phosphor powder and place in a plastic bag. Wipe the area with a damp paper towel to pick up stray shards of glass and powder and put the towels in the plastic bag.
