Easy to install if you have the right size hole saw (6.25"). a quick connector instead of a nut, but that doesn't matter. Other brands have a quick connector. I've installed over 40 of these and they work well, look good and have lots of light. I recommend the Essentials range over the Basic range if you want more light. I chose the 3K color (not adjustable) and we love it. Would buy them again.
