Have a roughly square dining room opening to the kitchen on one side and French doors to an outdoor patio on an adjacent side. The dining room is quite dark despite the French doors and a window in the dining room.

Wanting to add a sun tunnel to let in some more light - but where would I put it so that it complements a pendant over a central dining table? Don't want the expense of a full skylight or multiple sun tunnels - the room is about 4 x 4 m.
