In the United States and Canada, the Energy Star program labels lamps that meet a set of standards for efficiency, starting time, life expectancy, color, and consistency of performance. The intent of the program is to reduce consumer concerns due to variable quality of products. Those CFLs with a recent Energy Star certification start in less than one second and do not flicker. "Energy Star Light Bulbs for Consumers" is a resource for finding and comparing Energy Star qualified lamps. There is ongoing work in improving the "quality" (color rendering index) of the light.
