The FTC proposed new output-based labels for light bulbs in November 2009, and says that the new regulations will come into force in around one years’ time from now.
Under direction from Congress to re-examine the current labels, the FTC has devised new labels for light-bulb packages that are intended to enable consumers to save money by selecting the most efficient lamps that best fit their lighting needs.

The new front-of-package labels also will include the estimated yearly energy cost for the particular type of bulb.
Meanwhile, the back of each package of light bulbs 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:
- energy cost
- the bulb’s life expectancy
- light appearance (for example, if the bulb provides “warm” or “cool” light)
- whether the bulb contains mercury.

The lumen is the unit of luminous flux (effectively the total light output), while brightness or luminance is the luminous intensity per unit emitting area, and is actually measured in candela/m2 or nit.
