I know it's in the description, but I wasn't looking for the color feature at all when I bought these. Wanted warm white, and 2700k was perfect. Great lights. No weird buzzing noises, and very quick to turn on. Can't speak to energy efficiency or longevity, but they certainly don't put out the heat that the fluorescent bulbs before these do.
