Three pendant lights with 120 volt to 12 volt transformers in each unit. Uses 12 volt 50 watt bulbs. Units are in excellent condition, easy to install and includes 3 used bulbs (one in each unit) and 2 extra new unused bulbs that cost around $15.00 each at local stores. Lights cost about $125.00 each when new. Reason for selling, we wanted LED lights and a change in design.
