    Do I replace the ballast?

    I have narrowed the fault down to the ballast in this fitting. See picture. I cannot find an identical ballast. Blimey, there must be hundreds! Is there a similar ballast I can use?

    I have a bathroom mirror with 2 x 21W fluorescent T5 tubes and an IR sensor. The tubes switch off after a few minutes. I have changed the tubes and the fault persisted. I checked the output from the IR switch and it was 240V so that leaves the ballast as faulty. The problem is the ballast is...
