Sylvania. The Dulux EL CFL lamps come in a variety of wattages and types, from general purpose and directional to décor and specialty. This line of lamps includes the Micro Mini, the smallest CFL available, the company claims. The 13-watt version is approximately one-third smaller than the average mini-twist or mini-spiral CFL, the manufacturer says. This Energy Star-rated bulb can last up to 12,000 hours and saves homeowners up to 75 percent in energy costs over standard incandescent lamps. 800-544-4828.
