These are nifty little lights!  The standmount is plastic but since they sink into the ground so it’s really of no concern. The tops are chromemetal. The lights are pretty much flush to the ground and provide a great deal of light! They worked the first evening after only a half day of sun. I’ve got four of them positioned around 2 large trees in the backyard and they are a very nice attribute to the evening atmosphere. I intend to order another pack! One tree only gets early morning sun and then turns to shade after noon. The lights work just as well around that tree as they do the tree that is in direct sun all day. For the price, I’m quite satisfied with my purchase.
