An ENERGY STAR certified 60W replacement bulb retailing for $6 or below will have a payback of a year or less.
By changing one bulb you can save between $30 and $80 in electricity costs over the lifetime of the bulb.
For the best payback, use ENERGY STAR certified light bulbs in the fixtures that you leave on the longest.
The average U.S. household has more than 50 light bulbs — think of how much you could save in your home if you switched them all to ENERGY STAR certified models.
