I literally just finished screwing in the fourth light (was planning on doing 4 then seeing how it looked, add the other 2 later) and was tapping in the wire guide to hide the first wire when one light became super bright. I cycled the dimmer a few times with no help, it was twice as bright as the others. Unplugged it, plugged it back in, and the bulb blew. Annoying I thought, but not the end of the world.Well, it took out the rest of the unit so now none of them work. Just wasted an hour and a half installing them, though at least I didn't spend another hour hiding the wires before this happened. Reading the other reviews shows that this set is literally junk, don't bother because you're just going to waste your tim installing something that won't last. Maybe you'll get more than an hour out of them, but sounds like eventually you'll have to replace them.On the other hand, they did look great for the 5 minutes they worked!
