With the advent of compact fluorescent light bulbs, LEDs and other energy-saving lighting, marketers have relied on marketing schemes that might say a bulb is "equivalent to a 45-watt light bulb."
But those days may be coming to an end as the Federal Trade Commission has proposed a new output-based label for bulbs, which would guide consumers on the light output of a bulb, rather than its energy use.
The FTC is calling for comments on its proposed rule, which would emphasize lumens instead of watts as a measure of bulb brightness.
FTC would also require wording on the bulb itself, as well as packaging, that indicates not only the lumens but also a mercury disclosure if the bulb indeed contains mercury.
The back of the package would have a "lighting facts" box similar to the Nutrition Facts box on food items (see image).
The FTC is taking comments through Dec. 28. Here is a link (PDF) to the notice published in the Federal Register.
