I go through a lot of these bulbs with my kitchen lighting. They are used in the under-cabinet lights and the pendant above the counter. About a year ago I replaced half of them with LEDs. This increased the life of the regular bulbs considerably (lower currents in the system means less wear and tear, so the speak). But they still burn out. These bulbs are a perfect replacement. They seem slightly less bright than say the GE brand that you get at the hardware store or the IKEA replacement bulbs, but the difference is barely noticeable. I give them a thumbs-up.
