I have a chandelier with three large shades. When you are seated you stare up at the light bulbs. I hated that. The diffusers from 1800 Ceiling are perfect. They fit inside the shade exactly, make the light fixture look much more finished, and also soften the light on the table making dinners and dinner parties much more enjoyable. The diffusers were easy to order, came quickly, and were very well priced.
The rings were just what I needed to finish off around some duct work.
