The light fitting looks great. The flat circular plastic diffuser sits at the bottom of the fitting and is held in place with a circular ring of metal. This ring needs to be pushed down from inside the shade. A bit tricky. I used a ruler to push it down flush. When bulbs need replaced this diffuser probably needs to be removed as it would be awkward to get your hand into the shade, over the top. Having said that I believe the semi flush fitting is worth it.
