03648 - A03648. These Westinghouse 25 watt light bulbs are dimmable. This R14 shape bulb utilizes a brass base. Unlike an aluminum base, a brass base won't freeze or corrode in the socket, even after thousands of hours of use.
These bulbs are hard to find, when you find them they can be expensive per bulb. By buying 10, I was able to get them almost half price per bulb, now that a great deal and will last me a long time.
