… and that word is girandole.
A girandole is a type of wall sconce for use with candles. Typically, girandoles had a backing made of mirrors or tin or some other reflective material that would increase the candles’ light. They were commonly used in public rooms of a house, such as dining-rooms and ball-rooms.
An English Regency mirrored girandole with convex bull’s-eye mirror.

That’s interesting. Hadn’t heard that one before.
Me, too; but so glad to find a different word to use than “sconce.”
Yes, I know what you mean!
