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?

I hear lots of stories about panels failing, and so avoid any "special"
fitting.

That is the reason why I purchase fittings that take standard LED lamps
where the fittings will likely outlast the building they're in.

I shall be shortly installing somelights, these will use standard
fluorescent fittings to take standard LED tubes. If one fails I don't
have to change all the lamps in 5 years time for the sake of one to
ensure the batons matched.
