These circa 1920s to 1930s porcelain light fixtures were made by Underwriter Laboratories and are from their design or pattern "Porcelier." This is an Art Deco style, perfect for a renovation of a home from this era. All of the fixtures still have sockets, I do not know if these have all their hardware and are in working condition once hooked up, but they appear to be in really nice condition.

The round ceiling fixtures measures about 5-3/4" in diameter. The wall mount is about 5-1/2" tall and extend from the wall by a little over 4-1/2".
