Saving Energy with CFL light bulbs
Light Bulb


Lighting accounts for around 9% of the power usage in a typical home. You can reduce this by being sure to turn lights off when not needed, not leaving lights on when you are not home, moving to lower power light bulbs, and not leaving lights on all night.

CFLs - Compact Fluorescent Lamps

Replacing your traditional incandescent light bulbs with lower power fluorescent light bulbs (called CFLs or Compact Fluorescent Lamps) can be a great way to save power. The typical compact fluorescent light bulb will use around 20% of the power of a comparable traditional light bulb (i.e. one that has a similar light output).

CFL technology has come a long way in the past few years. Both the quality of the color of the light as well as the light output has improved tremendously. CFLs can fit right into your existing light sockets. There are also CFLs of different shapes sizes and CFLs with covers (so they don't look funny).

CFLs typically cost 3 to 10 times more than the average incandescent bulb, but they also last a lot longer. A typical CFL will last 8 to 15 times longer than traditional light bulb. This savings, plus the money you will save in power, make CFLs a lower cost option in the long run. It also means less trips to the store for new bulbs for replacements. If you don't want to spend the money today to replace all your light bulbs with compact fluorescent bulbs, then try replacing the lights that are on the most in your house. This will give the most bang for your buck, and will also mean less changing of those oft used lights.

Note: The life span of some CFLs may be reduced if you turn the light on and off too quickly. Some manufacturers suggest that you leave CFLs on for at least 15 minutes.
