These work great with a flameless candle with a timer.  We are not using them as typical sconces because they were too large for the way we intended so we hung them higher up on the wall by our staircase (one is on a post and one is on the wall) and they look really neat!  We love to sit on our couch in our living room in the dark with these lit up, listen to nice music, and relax.  Very nice!     

Pros: Neat look 
Cons: Best to use with a flameless candle with a timer, otherwise it would be inconvenient to light them.
