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 a not one of the long ones but a shorter one that fits neatly inside a waterproof compartment. I cant get a replacement ballast so I'm looking for some options. I want to replace the Fluorescent tubes with LED T5 equivalents but UK ones still seem to require a ballast (presumably to make them a straightforward replacement). It seems that the US have type B tubes which will run straight off the mains (that would be an easy option as I could just remove the ballast and adjust the wiring but they don't seem to be available in the UK. Can anyone suggest an alternative? Thanks
