Someone gave a very similar version of this a bad review and said there wasn't enough light. We found it gave what we expected from a 100-watt bulb and it's rated at 150 watts. Another person reviewed it as cheap and flimsy on the Home Depot website. All you have to do is hold the bulb in the ceiling. The instructions are a bit complicated but overall the installation was easy and it's smart how everything can be done under the covers if you have a hole and wire. Stay close to hook it up.
