球泡灯Lighting Facts Labels能效标签

The Federal Trade Commission (FTC) program

This applies to all bulbs with a medium screw base, which is the base type used for the majority of household lighting. After January 1st, 2012, this label will be mandatory on all applicable products sold in the U.S. This label will replace the DOE label on all LED bulbs with a medium base.

The FTC labeling will be found in three places: On the front of the packaging, a lumen or ìbrightness? listing and estimated yearly energy cost will be required. On the back of the packaging, information on brightness, estimated yearly cost, wattage, light appearance, life expectancy, and whether or not the bulb contains mercury will be required. On the bulb itself, the lumen output and a disclaimer on mercury-containing bulbs will be required as well.

The Department of Energy (DOE) program

This applies to all LED products, regardless of base type. It is a voluntary program, manufacturers are encouraged to participate but it is not required. It is primarily directed to retail buyers, utilities, and lighting professionals, but the label contains information that is useful to consumers as well.
