I bought 4 of these to replace lighting in a church I am restoring after it flooded.  I wired them to one dimmer switch.  They were reasonable priced and on excellant quality.  Wayfair was great about seeing that I got everything I needed.  They arrived undamaged.  They are time consuming to put up because of the 172 Crystals that had to be hung alternating one small and then one large.  I am very pleased the purchase and the service from Wayfair. Now all we need is out new pews.
