These lights are very easy to connect and install. They are very thin but also very durable. They have very strong spring clips that hold them securely in the hole. The light is very bright but can be used with the dimmer which I will be using. I bought a hole saw to cut holes, which takes practice, so I suggest using drywall scraps to practice cutting some holes. Junction boxes can be connected, then connect the light to the junction box, fold and assemble springs. Very easy. So easy for a caveman! I'm a girl, I bought them, they seem to be well constructed.
