These light bulbs were a suggested item for a vanity fixture I purchased. When I got them they did not fit the vanity size or style at all and hung out the bottom. A regular light bulb is what this vanity fixture needs. I will be returning them. Just make sure they are the type of bulb you need for your fixture size and style. They also are not a traditional warm white glow, they are a much darker glow and the glass has a brown tint. Not good for a bathroom vanity light, in my opinion.
