"Turned the light on yesterday and an interesting BANG! Fizz-fizz-fizz-POP! from the light fitting.
To be fair, it's been good and was better than the old magnetic ballast fitting it replaced, with pretty immediate light rather than the characteristic flicker start seen with the older ballast. However, I'd prefer it to last more than thirteen months, the one it replaced lasted thirteen years.
It also seems to be a shame that I have to junk the whole thing when it's just the ballast that's gone"
