To help make the right choice the Federal Trade Commission (FTC) requires that light-bulb packages show bulb ratings on wattage, lumens, and bulb light. As a consumer you should know what you are buying:

Wattage: Many people think the higher the wattage, the brighter the bulb. Wattage doesn't measure the amount of light from a bulb but rather the amount of electricity going into the bulb.
