When we bought this house, the living room has no ceiling light, we use lamp shade for lighting. I hoped this will replace our lamp shade. It was great when I installed it during day time, there are 2 types of lighting: ambient and task lighting and for both, they have 3 levels of brightness. And then, there will be night motion sensor and daytime sensor. Everything is great except when I tried it at nightime, it does not really give me the light I need in my living room. So I guess, it still has a purpose which will be going down our basement lighting.
