Went back out to my garage yesterday after lunch, switched on the lights and nothing. The circuit breaker for the lights had popped. I reset it, turned the lights on and there was a pop and blue flash at the end of one of the flourescent tubes and it popped again. The transformer was also bloody hot with that smell of hot electronics in the air. Does this mean the tube is gone or the whole fitting is junk? Its probably about 40 years old as it was one salvaged from the kitchen when we redecorated and rewired a few years ago. TBH I need to stick an extra one up as the front of the garage is a bit dark (the busted is a single 4 footer at the back and theres a double five footer in the middle) Any suggestions as to a cheap place to buy these?
