I will not plagiarize all the above comments but I will strengthen the nail on the brightness. The price / quality ratio is excellent ... but do consider the light output. This is not a natural white but cold !! Our target audience these bulbs for the show: "It does not do!" Brightness is that expected but the "white" is so intense that the colors in your room-to-eat are hyper attenuated bland: a board for this type of part, choose "Warm White". Never mind, bulbs regain a corridor and I will redeem the same product in warm light. If the installation was no problem and all the bulbs worked. Last, do not buy in a hurry because the delivery is long despite the seriousness of the supplier.
