My son was complaining about the light in his room. When he was younger he had picked out the version that has 3 lights that look like spot lights. He was unable to light the entire room. I got him this one and he is VERY pleased with it. A semi-flush hangs just low enough to bounce the light across the ceiling into the room. Light fills the entire room. I did not pay attention to the diameter of the light, only the power of the light. It is a smaller diameter light. Since it's in a small bedroom, this is not a factor. I just don't think it would look as good in a large room. The other thing that was a nuisance is that the bulbs do NOT come with it. He had to make a special trip to the hardware store for them.
