I started the thread http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17517 because of what seems to be a dead under cupboard light and figure that LED replacement may be the way to go.

However, of the five lights, only one is dodgy and that does sometimes turn on, but after X minutes, starts to flicker and dies.

I figured it was the starter but as they are very small lights, there is not starter, just a bunch of electric bits and a ballast. Obviously, as it does come on (sometimes) the problem is either a poor connection (I did check them all and they seems fine) or something else, but I have no idea where to start to isolate the component and may be , find a replacement.

Any ideas gratefully taken on board.

Agreed is seems like the ballast; can these be replaced?]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17536&Focus=297200#Comment_297200 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17536&Focus=297200#Comment_297200 Sun, 14 Aug 2022 16:16:33 +0100 djh
One other simpler test to try first is just to rotate the tube back and forth slightly to see if the light comes back on.

Posted by me: "You could check by swapping in one from another fitting" - sounds like you have four other lights that you can borrow a working ballast from?]]>
