Color temperature is omitted from the listing of "Luminous Flux". They are so cold that my beige wall paint looks blue-green. Also, the ballast is so large on a standard base that I have had to remove the harp and lampshade from several table lamps and leave them removed to use them. If you can solve these problems, the light bulbs will burn brightly.
