Better Globes Calculator

Compact fluorescent light globes (or CFLs) use 80% less power – and can last up to eight times longer – than standard incandescent globes. This calculator will help you learn how to save money and reduce your household’s greenhouse gas emissions by choosing CFLs in your home.

After using the Better Globes Calculator, you can find out more about CFLs in our tips on changing your appliances – or learn about our globe recycling initiative which encourages you to recycle CFLs after use. If the calculator does not appear below, you may need to download Adobe Flash Player.
