I really love the look of the Robert Abbey Drexel 16" wall sconce. It has 2 40-watt bulbs in each sconce. If I use 2 of these fixtures (hanging vertically on either side of the mirror) in a 5 1/2 x 7' powder room, do you think it would give off enough light? It is the only room in our home without a window. They also sell a larger version at 24" long ea with 4 40-watt bulbs each but they are expensive ($193 ea for small version, $355 ea for large version) so I would rather purchase the smaller ones if possible.
