I bought 4 of these for our kitchen:
3 of them have failed, and Amazon have agreed that I should return the lot, including the replacements I bought.
They are circular panels (36W 3240LM 4000K). In retrospect, they are a bit too bright, so I'd settle for lower wattage. These ones allegedly have a 20,000 hour lifespan.
Can anyone recommend some reliable lights that look similar, but actually work, please?
