I’m not sure why this is called a ‘barn’ light, as it looks NOTHING like what you would see on a barn.  However, the shape, black & brass metal, and Reeded glass do make it look Art Deco, which is what I wanted.  We didn’t install ourselves, but our electrician had no issues.  They are very good looking and provide plenty of light.  The only thing I was not fully happy about is that the large size is not as large as expected—-it was a little hard figuring out the dimensions since it is a ball.  We thought it would be same or bigger than a basket ball & it wasn’t.  They are certainly unique—-you won’t find neighbors with the same lights.
