By replacing your home's five most frequently used light fixtures or
bulbs with models that have earned the energy, you can save $75
each year.
Compared to traditional incandescents, such
as halogen incandescents, compact fluorescent lamps (CFLs), and light
emitting diodes (LEDs) have the following advantages:
-
Typically use about 25%-80% less energy than traditional incandescents, saving you money
-
Can last 3-25 times longer.
Today's energy-efficient bulbs are available in the wide range
of colors and light levels you've come to expect. While the initial
price of energy-efficient bulbs is typically higher than traditional
incandescents, newer bulbs cost less to operate, saving you money over
the life of the bulb. Many of the newer bulbs last significantly longer
than traditional bulbs, so you won't need to replace them as often.
The table below compares a 60 watt (W) traditional incandescent with energy efficient bulbs that provide similar light levels.
