Hi I've checked other posts but not quite the same, if the kitchen four light spot bar hasn't been on for a few hours it flickers for two minutes then settles down, whereas if I turn the other kitchen light on they stop flickering straight away. At the same time the Lounge light will flicker twice then is ok. I have changed bulbs from 50w to 35w. A replacement fitting is £18 if It's easier to swap the whole unit is it easy to do? Thanks Andy
