Get ready to learn a new way of communicating about light.
Starting in January 2012, light bulb advertising will use the term “lumens,” instead of “watts,” to describe a light bulb’s brightness.
With various kinds of light bulbs on the market, the Federal Trade Commission came up with lumens as a way for consumers to compare bulbs.
Consumers have long relied on “watts” to help them choose the right bulb for their indoor and outdoor lighting needs. Watts refer to how much energy a bulb uses when lit; lumens measure the amount of light produced by a bulb.
Lighting packaging will now indicate the lumens produced by a bulb, so consumers can compare bulb types to find the right light for their needs.
