I am this ceiling fixture, one of those "serpentine" units you can bend in curves. It had 5 lights hanging from it. They were 12v, 20 watt bulbs. EYC/CG covered glass reflectors. A couple of the bulbs were burnt out , so like "Tim Allen" , I wanted more power too. So I, YES I , put in a couple of 75 watt bulbs. In one minute the whole unit went dark. I checked the circuit breaker OK, the little 5amp fuse in the transformer case was good too. Is the transfomer burnt? Are these units that touchy ? Any help really appreciated !!! This light fixture is in my WIFE"S kitchen! help!!!!
