I had horribly ugly lighting in my house. It fits perfectly into the body and the lamp insert is simply screwed in. This is my first time using modified LED lighting. It is very bright as advertised. I use it with a Lutron Caseta Smart Dimmer. There is no neutral wire in the junction box, so Caseta is the best option for smart lighting. This light turns off completely on the lowest setting and is very bright on the highest setting. I didn't have to adjust anything on the dimmer itself. That works great. That was the main question I had before buying. My only gripe is that adjusting the gimbal to direct the light doesn't make as much of a difference as I might expect. But it works. For the price you can't complain.
