Lighten up with CFLs
Practically since its invention, the traditional pear-shaped, incandescent light bulb has been a household staple, used in the majority of fixtures we use to light up our homes. Yet, incandescent bulbs are actually better at producing heat than light — in fact 90% of the energy they give off is heat. That wasted energy is money you are throwing away.
Save money on your energy bill by purchasing ENERGY STAR® qualified compact fluorescent light bulbs (CFLs). CFLs screw into standard lamp sockets, and give off light that looks similar to the common incandescent bulbs — unlike the fluorescent lighting we associate with factories, offices and schools.
Highly efficient and long lasting, today’s CFLs offer the benefits of fluorescent lighting while producing a steady, quiet, warm white light.
- CFLs last up to 10 times longer than incandescent bulbs.
- CFLs use up to 75% less energy.
- CFL bulbs are now available in a range shapes and sizes —as well as light colors.
- CFLs pay for themselves in less than nine months.
- Using CFLs in the five fixtures you use most often can potentially save you more than $65 per year.

- Match light bulb wattage to your lighting needs.
- Concentrate lighting in reading and work areas.
- Dust your light bulbs regularly as dirt absorbs light and wastes energy.
- Turn off lights when leaving rooms.
