Why do the instructions sheets say not to use the lights on trees made of metal or with leaves or needles made of metal. Does this mean I can not use them on artificial trees?
This is a marking required by UL (safety testing lab), and is intended to warn against the use of lights on the old style silver metal trees that had metal needles as this can be dangerous. Artificial trees with PVC or Mylar needles are not included in this warning, so it is ok to use on these types of trees.
