Over our dining room table, we have a weird looking light with 3 halogen lights. One of the lights burned out yesterday. Mrs went to the store and bought new lights and put them in today. Suddenly this evening, the new light bulbs went out. After an observation, there is a little sticker on the light sockets that states "use 20 volt bulbs". Mrs used 50 volt. What is the failure and can it be repaired? I paid a lot for this light and to have it installed. HELP!!!!!!!!
