These are very nice 5000K daylight bulbs at a good price. I have used CFL bulbs for many years for the energy-saving and for the convenience of not having to constantly change light bulbs. I actually hadn't bought bulbs in years until now. My old bulbs were the yellowish color, but I wanted the bright white for this purchase, and these did the trick. There is quite a difference. These bulbs make the kitchen much cheerier in the gloom of winter, and actually seem to ease some of the seasonal depression that occurs with the lack of sunlight. I will be replacing more of the yellow ones as they wear out.
