Compact Fluorescent Light Bulbs (CFLs)
ENERGY STAR® qualified compact fluorescent light bulbs (CFLs) use about 75 percent less energy than standard incandescent bulbs. This means that each light bulb you change to a CFL will help reduce your utility bill. By replacing your home’s five most frequently used light fixtures or the bulbs in them with ENERGY STAR qualified models, you can save $70 each year. The average home has approximately 30 light fixtures, so if you replace all your bulbs you will save even more!
ENERGY STAR qualified CFLs have other benefits, too:
- By using less energy, qualified CFLs reduce the greenhouse gas emissions caused by burning fossil fuels at power plants.
- Because CFLs produce less heat, they can also help offset cooling costs inside your home.
- Qualified CFLs are actually less expensive than incandescent bulbs in the long run, since they offer energy savings and last a much longer time. Using CFLs means you save on your utility bills, plus you won’t need to replace bulbs as frequently.
- CFLs last up to 10 times longer than standard incandescent bulbs, which make them great choices for busy folks or for fixtures in hard-to-reach places like high ceilings.
- CFLs are available in a variety of color options, such as soft white, cool white, or daylight.
- CFLs provide the same amount of light as an incandescent bulb.
- Qualified CFLs are tested to meet stringent criteria for energy efficiency and performance. They must meet standards for minimum product life, maximum start-up and warm-up time, color rendering, and other measures.
- Each ENERGY STAR qualified CFL comes with a 2 year warranty for residential use.
