Choose the correct bulb wattage When you buy any lighting fixture, check the maximum wattage it will take. A bulb with too high a wattage can produce excess heat that can create a fire hazard or damage the fixture. Remember, wattage is the indication of how much power a bulb consumes, not the amount of light it generates.

For the first time, the label on the front of the package will emphasize the bulb’s brightness as measured in lumens, rather than a measurement of watts. “While watt measurements are familiar to consumers and have been featured on the front of light bulb packages for decades, watts are a measurement of energy use, not brightness,” stated the FTC in its press release. “As a result, reliance on watt measurements alone make it difficult for consumers to compare traditional incandescent bulbs to more efficient bulbs, such as compact fluorescents.” The new front-of-package labels will also include the estimated yearly energy cost for the particular type of bulb. The back of each package will have a “Lighting Facts” label modeled after the “Nutrition Facts” label that is currently on food packages. The Lighting Facts label will provide information about: Brightness Energy cost Life expectancy Light appearance (for example, “warm
