Expect to see LED light bulb packaging sport a new label this summer. The intent is to introduce some transparency in the market and guard against exaggerated claims in lighting performance.
This should lend some clarity on lumens, (a measure of the light output) how many lumens per watt, helping us better understand the bulb’s efficiency as well as the light color. One of the arguments against migrating away from incandescent has been the quality of the light. Hopeful labeling will help shed some light on this subject (sorry I couldn’t resist).
