It is not easy to say that one light is better than the other when it comes to flush lights and recessed lights. Flush lights are more flexible. You can find them in a lot of different styles, designs, and sizes. But if you don’t want the light to affect the design of the room, then flush lights are not a great option. If that is your priority, then recessed lights are the way to go. But it is not easy to install recessed lights on a concrete ceiling. You will need to make a recess with at least six inches of space for the fixture. The size limitation of the recessed lights also means that you cannot go beyond a certain level of brightness.
