Installation was pretty easy as it allows for a 2.75", 3.5" and 4" junction box, including all the hardware. it's quite bright when viewed directly (don't do that) but I wish the diffuser was of a higher quality as you can see the square on/off LED board. Another 5 stars for excellent quality for the price and installation! We'll let you know how long they last in a few months! Installed March 6, checked March 9, 2020
