Ordered 4000k first and felt they were stark white in my room. I replaced them with 3000k which has an acceptably warm color but I would probably prefer 2700k. The six sets of lights have replaced the 4-track lights, and the "spots" are adequately spaced, with no glaring bright spots. I don't use a dimmer.
