Don't miss your chance to get FREE CFLs.
Saving energy and money can be as easy as changing a light bulb. One of the easiest ways to lower your energy bill is by replacing your standard bulbs with compact fluorescent light bulbs (CFLs). We’re committed to helping you use energy wisely. That’s why we’re giving eligible customers free CFLs to boost your home’s energy efficiency. To see how many bulbs you qualify for, complete our quick and easy sign-up process and receive your CFLs in four to six weeks at your home.
An ENERGY STAR® qualified CFL saves about $30 over its lifetime in energy costs. Replace your home’s six most frequently used bulbs with CFLs and watch your savings grow to $180 over the lifetime of the bulbs.
