These teacup lights are a really unique and eye-catching piece! Buy a light kit and install it according to the directions, or have an electrician install it for you. Once your kit is installed, you’ll need to look at how the shades are fixed to the lights. For cutting the holes, use a diamond drill bit. Use a drill press for this, it make it super easy to hold everything steady, but you can totally use a hand drill as well. If you’re using a hand drill, start the bit at a slight angle to get things going, then straighten the drill out as soon as the cup begins to be cut. Read what to do in the source.
