Consumers seem to get lost in the confusion surrounding regulations regarding incandescent light bulbs. Incandescents were the standard just a few short years ago, but with energy regulations and the growth of environmental impact awareness, they seem to be on their way out.
According to the American Lighting Association, incandescent light bulbs must now meet stricter requirements for lumens and wattage (as of January 1, 2012). The regulations require incandescent bulbs to produce the same amount of lumens (see more about lumens here) for less wattage (energy output). So this means that, for example, the standard 100 watt incandescent bulb will now use no more than 72 watts and produce the same amount of light.
Also, during these changes, there were new packaging requirements enforeced throughout the U.S. for light bulbs. Instead of listing a bulb as a 72 watt, it is listed in lumens, “1500 lumens”.
The American Lighting Association has provided an excellent article going into more depth about the incandescent bulb changes, and can be found here.
