New U.S. Light Bulb Packaging
The U.S. Federal Trade Commission is requiring manufacturers of incandescent, compact fluorescent and LED light bulbs to use new labeling on consumer packaging by mid-2011 to help consumers choose the most efficient bulbs for their needs.
For the first time, the label on the front of the package will emphasize the bulb's brightness as measured in lumens, rather than a measurement of watts.
“While watt measurements are familiar to consumers and have been featured on the front of light bulb packages for decades, watts are a measurement of energy use, not brightness,” stated the FTC in its press release. “As a result, reliance on watt measurements alone make it difficult for consumers to compare traditional incandescent bulbs to more efficient bulbs, such as compact fluorescents.”
The new front-of-package labels also will include the estimated yearly energy cost for the particular type of bulb.
The back of each package will have a “Lighting Facts” label modeled after the “Nutrition Facts” label that is currently on food packages. The Lighting Facts label will provide information about:
* Brightness
* Energy cost
* Life expectancy
* Light appearance (for example, “warm” or “cool”)
* Wattage
* Mercury content
The bulb's brightness, measured in lumens, and a disclosure for bulbs containing mercury, also will be printed on each bulb.
