This is a beautiful vintage-looking large dimmable bulb. They have, at least with my lamp, three different degrees of brightness. They create a very lovely romantic and cozy atmosphere in my bedroom, and they are perfect to pace my getting up in the morning going from very faint light to bright one. My only criticism is that these bulbs are extremely flimsy and delicate and break easily. This is the second replacement I've bought in a year. For the rest, a beautiful atmospheric bulb.
