Sometimes the answer is just too obvious. We found exact replacements for our living room table lamps at the factory.
That's great!
Do you know if they have replacements for the clear half-round diffusers over the bathroom sink?
Dick,
I do not know that. Parts department will answer that question over the phone. And, if you are interested in replacing the glass shades on wall sconces, Lowes has some incredibly beautiful upgrades for only $10/shade.
