The light didn't work.  I got the run around to get it replaced.  It took over a week to finally get Exhart to ALLOW me to get a replacement.  I waited for the replacement to ensure this one worked.  Now a week later, my return is stating that it is too late to be returned.  Really!!!!  Don't buy from Exhart.  No worthy of your time.  Top ball is pretty, glass on bottom, doesn't light.
