CFLs and LEDs. CFLs only need one-fifth to one-third the electricity of incandescent's to produce the same amount of light and last about 10 times as long. "They start up initially, but takes them a while to warm up. So, to reach the optimum light output it's going to take a couple of minutes," said lighting designer, Don Dragoo. If you need light immediately in an area of your home, CFLs might be a problem. You could try an LED. They are 10 percent more efficient than CFLs.
