Static light with no options.
Funny you say that, I too took a minute to find the Crystal. You slide it in and then you clip to the tree.long Crystal's are at the bottom that's where you'll find the one to slide into . Merry Christmas
It is heavy. We found we had to give it a bit of extra support by attaching a thin wooden dowel behind it. We stuck the dowel down deep enough Into the tree to give it the support it needed and used small plastic ties around the dowel and the branch used for the star. Ours is a fake tree so we keep the dowel and the clip attached to the tree, ready just to add the star next year.
This is DEFINITELY COOL white, I would prefer the warm.
