DO NOT BUY! Lighting Universe aka ATG Stores has a terrible return policy, mon't make exchanges and the people are utterly un-helpful. Do yourself a favor and buy elsewhere.
DO NOT BUY FROM ATG! They would not accept a return or even exchange two unopened lamps past their precious "30 day" window. I have never heard of such a draconian policy! They were rude, inflexible, and I hope this review loses them LOTS of business!
