Edison type lighting using repurposed black pipe and brass pipe fittings along with UL approved lamp components. These lamps use a variety of Edison type bulbs that illuminate with a pleasant amber glow! All of my lights are ready to plug in and enjoy! No electrician is needed to hang these lights! The hanging Edison Pulley Lights come with 16' of cord and a rocker on-off switch. All lights come with either a 40w or 60w Edison bulb. Most of my desk lamps come with a water valve that is actually the on-off switch!
