The product description is inaccurate.  It indicates that is is compatible with a sloped ceiling but it is not.  When we asked customer service for assistance and clarfication, they told us we can make it sloped ceiling compatible if we find and purchase a part at a "store near us"...which basically means we are on our own.  So we purchased a light we believed would work in our space only to discover we must spend an additional 30+ dollars for it to work.  Not happy with the fixture or the customer service.
