Energy-efficient light bulbs have come a long way in recent years, and there are many different shapes, color temperatures, and even dimmable bulbs available. To help you choose the right bulb for the fixture and mood you want, ENERGY STAR has created an online Choose a Light Guide.
The interactive guide lets you choose a light fixture, such as a lamp, overhead light, or wall sconce, and then play with different shape and color options including soft white, bright white, and daylight. As each option is selected, the image changes to give you a sense of how that bulb would look, and the text panel displays informative details. The guide doesn't include LED bulbs, but it's a great resource if you're shopping for CFLs.
