The open lower bottom allows for a lot of light. A great upgrade piece and easy to install. When changing out the lightbulb though, you have to remove one of the black metal pieces to slide the bulb in and out. Not the most annoying task, but it is not as easy to change a light bulb as just unscrewing it and screwing a new one in.

Pros: Easy install, price, look
Cons: Replacing light bulb requires additional effort
