- Compact fluorescent (CF) bulbs are energy-efficient light bulbs.
- CF light bulbs use 75% less energy than old-fashioned light bulbs, and last five times longer.
- Most CF bulbs last about 6,000 to 10,000 hours.
- CF bulbs fit in most fixtures, indoors and out (check for the label on outdoor bulbs).
- CF bulbs can replace old-fashioned or halogen bulbs in most fixtures.
- For maximum savings, begin by installing CF bulbs in areas where lights are on for long periods, such as the kitchen, family room, and outdoors - especially your porch light!
- CF bulbs are ideal for hard-to-reach fixtures because they don't need to be changed as often.
- Look for the ENERGY STAR symbol on CF bulbs packaging.
Other advantages include
- long life
- low heat dissipation
- improved visibility
- resistance to shock and vibration
