We had an electrician install this.  The light never worked.  He finally told us it was defective.  So we called the number in the box which was to be called before returning it.  This was the Heath Zenith number and they sent us a replacement.  The replacement entailed another visit from the electrician - this time for only about 15 minutes, since this light worked.  This replacement has a price about $30 less than our first light.  So, we do finally have a working light, but it cost us $30 more than its price plus a total of about 2 hours of an electrician's time.  We know there is no way to recoup the labor cost, but feel that someone should be refunding that $30.
