No special wiring required. These lamps plug into your wall socket. Our pendantt lamps are top-quality. We use a 15½ foot vintage-inspired, fabric covered twisted pair lamp wire for the right look. With a UL knot and proper strain reliefs, you can hang our lamps with confidence. These are designed to easily hold the weight of our lamps. Each socket has a turn-key switch for easy on and off. Light bulbs are not included with any of our lamps. We also offer pendant conversion kits to easily turn your socket light into a more permanent hanging fixture. Light bulbs not included.
