Most of today's incandescent bulbs will be phased out by 2014 and replaced by New bulbs using halogen, compact-fluorescent and LED technologies. We all are accustomed to buying bulbs based on watts, which refers to energy usage. Well, that is going to change. We will all be buying our light bulbs based on actual brightness, which is measured in something called lumens.
To help with this new reality in light bulbs, GE this fall will introduce a dramatic packaging overhaul, organizing its light bulbs by lumen level using five different colors: yellow, green, blue, orange and purple. A watt-conversion will also be on the package.
Osram Sylvania will also color-code packaging based on the light's actual color (warm and cool). By 2012, the Federal Trade Commission will require manufacturers to post "Light Facts" labels on most bulb packaging with info about brightness, light appearance and annual energy cost, among other things.
