I ordered a Hope Suspension fixture by Luceplan on behalf of a customer in July 2016. The clear plastic panels on it are cracking and falling off. This was a $3000 light fixture including shipping and specific lightbulb. When I called Lumens they offered to sell the customer more panels. I realize that Lumens is not the manufacturer, but I would have expected more support for such an expensive fixture which is less than 2 years old
