My living room has no central overhead light but four wall lights, it's a rectangular room approx 16ft x 10ft. Each long side has two lights exactly opposite the lights on the other side. I'd like something that isn't glaringly obvious but at the same time has a bit of substance about it- with four light fittings and them being fairly close as it's not a massive room, I dont want to overpower the walls with lights. Any ideas?
