The product comes with all the necessary installation adaptors so it fits nicely into the space. Unfortunately for me, the light it replaces is much larger and the trim doesn't cover the hole. I wanted this for our shower, because the remodeler put in a warm 2700 degree K LED in the shower and all the rest of the lights in the bathroom are daylight. Since this is a daylight LED, I thought it would work great, since it is the same style, etc. At this point, I am still trying to figure out a way to make it work because, while being smaller, it is the same style as my current light. As to how easy it is to install, outside of the bezel problem, it should only take a few minutes to install. Just pull the old light out, screw in the adaptor, and snap the new one in. It is a quality product. But, I would recommend measuring your current fixture to make sure this one will fit.
Easy to Assemble, High Quality of Material, Very Bright, Well Made
bezel not large enough for my install.
