Easy to install if you have the right size hole saw (6.25"). They black out well. There was a problem with a missing clamp and customer service responded immediately. Good experience. Only suggestion would be a quick connector instead of a nut but that's no big deal. Other brands have a quick connector. I've installed over 40 of these and they work well, look good and have plenty of light I suggest the Essentials line instead of the Basic Li e if you want more light I went for the 3K color (not adjustable) and we love it Would buy again.
