I bought 4 of these fixtures to swap out horrible 'Tuscan' style dome lights.  What an amazing difference!  They are on the large size for my use in hallways, but because my ceilings are high and they are 'airy' they look fabulous.  I wanted fixtures without any glass so the New Mexico desert dust will not show and cleaning will be held to a minimum.  Installation was a snap.  We used 25 watt equivalent bulbs, as we found the 40 watt bulbs to be too intense.
