If you replace five regular 60-watt light bulbs with 13-watt ENERGY STAR® qualified light bulbs you can save more than 1,400 kilowatt-hours over the lifetime of the bulbs. That’s enough energy to:
Run your ENERGY STAR qualified clothes washer for more than seven years.
Light the average household for nearly nine months
A 23-watt CFL is just as bright as a 100-watt incandescent bulb.
