Q: That sounds pretty complicated. How will I know what to buy when I go shopping for light bulbs?
A: By the middle of this year, light bulb packages will be required to bear a lighting facts label designed to help consumers choose bulbs. The label is similar to the nutrition facts label found on food packages.
The label will show the number of lumens the bulb produces, the number of watts it uses, and the lumens per watt — a measure of the bulb's efficiency. It will also tell how warm or cool the light is and how true colors appear under the light. If the bulb contains mercury, the label will note that, too.
Eventually we'll get used to thinking in terms of lumens when we're choosing bulbs. For now, here's a conversion guide from the Department of Energy:
— Replace a 100-watt incandescent bulb with one that gives you about 1,600 lumens.
— Replace a 75-watt bulb with one that gives you about 1,100 lumens.
— Replace a 60-watt bulb with one that gives you about 800 lumens.
— Replace a 40-watt bulb with one that gives you about 450 lumens.
Q: Will the new bulbs fit my old lamps and light fixtures?
A: For the most part, yes, assuming your lamps and fixtures are designed to fit general-service bulbs. All three types of energy-saving bulbs — compact fluorescent bulbs, halogen incandescent bulbs and LED bulbs — have screw-in bases that are the same size as general-service incandescent bulbs. The bulbs are roughly the same size as the old ones, too, although some may be a bit bigger or smaller than what you're used to.
If you're in doubt, the Energy Department recommends taking one of your old bulbs with you when you shop so you can compare or get assistance from a salesperson.
