Compact Fluorescent Lamps (CFLs)

Compact Fluorescent Lamps are a quick and simple way to implement energy efficiency measures into your home. However, if you are unfamiliar with CFLs and how they compare to a standard incandescent bulb, you may find yourself to be overwhelmed when you visit your local retailer and see the vast selection of choices available. It is helpful to know what your lighting needs are, and to understand the equivalencies between CFLS and incandescents.
