The 60W equivalent (800 lumens) Micro Mini CFL uses 13W of electricity and produces light with a color temperature of 2700K, just like a conventional incandescent. The company says the lamp's phoshor formulation generated warm color tones and a color rendering index of 82. The instant-on lamp contains 1.5 mg of mercury, which Osram Sylvania says is the lowest in the industry, and should last 12,000 hours, or 11 years. These CFLs come in spiral, BR lamps, and 3-way models in wattages from 5 to 33.
