Well I am my electrician, by trade, and picked out these sconces for my wife to replace old candle holders we had. 
Piece of cake to install, which if you’ve installed as many types of fixtures as I have, you’d appreciate the simple ones. 
The glass is somewhat thin, makes me a little nervous should anything happen to it. I don’t believe it is, in any way, a safety glass. 
Overall happy with the purchase. On to the next project.
