The newer compact fluorescent lamps (CFL) are more energy efficient than the conventional incandescent type lamps. However, there are some tradeoffs to be considered. CFL lamps usually have a different color spectrum than conventional “A” type incandescent lamps. They are slower to warm up (not “instant on”), some cannot be put on dimmers and, if the temperature falls below freezing (outdoor lighting or lights in a garage or shed), they may not turn on at all.
Disposal of CFL lamps are subject to hazardous waste rules and regulations in many communities; you may need to take these to a special disposal site instead of just tossing them into your trash.
On the up side, using the same formula as above, you can see that CFL lamps can reduce energy costs substantially.
A 26-watt compact fluorescent lamp (CFL) is roughly equivalent in light output to a 100-watt conventional light bulb. Burning 24/7/365, that CFL lamp uses 227.14KWH, or about $27.26 per year to operate. Quite a difference.
Now obviously your lights aren’t on for 24 hours a day, unless of course you have teenagers living at home. But you can see that it does add up.
