We bought 4 lights to go over two islands in our kitchen.  The ceiling is vaulted.  They are very pretty and make lovely patterns on the ceiling at night.  Only issue is the increments of the lighting stem sections is limited and therefore hard to line up ours due to the vaulted ceiling.  We will need to modify the stems somehow so the lights can be evenly spaced.  They can't just be cut because they have threading and screw together. I wonder if it is possible to buy other lengths of stem sections?
