We got a pair of the 14" and 18" and love them so far! My husband said they were extremely easy to install because we could reuse the existing openings. The only frustrating part was figuring out the size of the LED bulb needed to fit through the bottom of the lantern. I kept buying the correct base to fit but it was an A19 size bulb needed for the 14". We are going to order another pair of the 14" for our rental unit now that it's getting darker here earlier in the Northeast. that makes a total of 8 lanterns! The true test will be through the first winter.
