Good: - They give a lot of light - No problems with the gap to install - They are inexpensive but Bad: - Spring clamps do not hold the lantern flush with thick drywall 1/ 2 inches. Spacers were required to give the springs additional tension. The foam gasket is useless; I removed it and applied a small coat of paintable sealer around the perimeter to seal the canopy. - I installed eight of these on 2019-11 and three of them died within two weeks in October 2020. They start flickering, turning on and off while the other lights in the circuit are still on, and then turning off. I would happily pay more for longer lasting lights.
