The exterior light bulb must fit through the opening of the vase. Take a bulb with you shopping or make sure it fits through old vases you already own. Find one vase that stands out and make that your centerpiece for the chandelier.
A hole needs to be drilled into the bottom of each vase to secure the light bulb and connect it to the lighting wire. Using a glass diamond bit and a small amount of water, drill carefully into the center of each vase. Press gently down as your drill the vase.
Using eyebolts, hang chandelier from top of patio or gazebo, run wire at different lengths for a staggered look. Use galvanized wire to support the weight of the chandelier, so the lighting wire doesn't rip out of the vase. Run wire to the transformer.
