The two smaller lights work but the large one has an issue. Since I did not get it installed within the 30 days allowed under the Wayfair return policy, this was money flushed down the drain. The large light flashes quickly on and off and twice in the last week it lit after flashing 20 minutes or more; those occasions I left it on and left the house. Essentially, it has made my roommate refuse to use the dining room light since it almost instantaneously gives him a migrain and he feels like he is experiencing some torture technique.
