Very nice lights that fit perfectly on top of the deck posts.  Don't give a lot of light, but a nice effect at night.  The light come with batteries, but because the lights screw in place, you do need to unscrew and remove them to replace the batteries.   They also look nice placed on a tabletop or around your yard.   I was a bit disappointed that the case is plastic and not metal.  I ordered the black and they look very nice.
