Switching to compact florescent light bulbs is an almost cliché way to showcase your environmental efforts?but just because it's shorthand for an easy way to go green, that doesn't mean it's not effective. CFLs give off just as much light but use fewer watts than incandescent, so they cost less to run and give off less heat?plus, they last as much as 10 times longer. But how can you get just the right energy-saving glow? Read on for an easy breakdown, and for an estimate of how much you'll save over the life of the bulb by switching just one. (Estimates found using the Bulb Savings Calculator from the Environmental Defense Fund.)

Why We Like It: The Long Life Energy Smart Spiral Bulb from General Electric is a solid choice for an all-around bulb—it works in floor, table, and ceiling lights, wall sconces, and covered outdoor lights?and is approved for restaurants, facilities, offices, and shops.
Eco-Factor: This Energy Star-rated bulb gives off the light of a 100-watt bulb using only 26 watts—plus it lasts as long as 12,000 hours, so you won't have to buy them very often.

Why We Like It: If you're swapping out floodlights, try EarthTronics' Outdoor Compact Fluorescent to keep your property bright without running up your bills; the bulb also replaces a 90-watt bulb in recessed or track lighting.
Eco-Factor: EarthTronics promises its bulbs will save more than 75 percent of the energy you're currently using over the 10,000-hour life of the bulb?plus the company donates 1 percent of sales to environmental initiatives.
Expect to Save: Since the EDF site doesn't offer a 90-watt option, we'll stick with EarthTronics estimate: $67 and 985 pounds of carbon dioxide
