The Marist 4-Light Semi-Flush Mount is perfect in my entryway!  I have 9" ceiling.  It is about 15" from top to bottom.
The prisms are likely glass (but it's amazing how they shine).  I had a can light in the location I wanted this light installed..
so the electricity was already there.  Everything arrived in perfect condition.  Comes with just one replacement prism in the small size. (also 4 large size on the fixture).  NO LIGHT BULBS ARE INCLUDED.  Get 40W candelabra type that look
like fire, clear.  This was my first Joss and Main purchase.  I'm very happy!
