Since the Fluorescent lamp was 65 watt fat tube and the new 58 watt tubes do not last long with a 65 watt wire wound ballast, plus poor access I decided to swap for a LED tube it was a drop from 5240 lumen to 2400 lumen and 24 watt, but bright enough for area.
It was installed around 3 years ago, but the house has been unoccupied for 18 months so not used that much, wife says yesterday it started to flash, today failed completely other fluorescent on same circuit working fine.
This is the first mains powered LED lamp to fail on me. But it has lasted less time than fluorescent tubes and a lot more expensive. The old ballast was removed so direct supply 230 volt. I see screwfix no longer do them, now they have a smaller 20 watt and 2000 lumen version. Which is 14 mm shorter so not sure will fit?
In view of short life I wonder if better fitting a new HF fluorescent fitting and abandoning LED? It would be brighter, and cheaper to renew tubes in the future. I was surprised at the way it failed, would have expected some LED's to fail and some keep on working, would seem the driver has failed, wonder if some back EMF from other fluorescent on same circuit has damaged it.
But before clearing floor and swapping the fitting, thought I would ask what others have found.
