We're in the UK, 240v lighting feed.
We have replaced all the lights in our house with LED ceiling panels.

These are pretty much the standard ligthing throughout our house with the exception of our Kitchen which has a dual controller 50-80w x2.

The issue that we're having is that two of the panels, the kitchen and one of the above, seem to go into standby mode on the 4th switch on.
They all have three light settings, Bright/Warm/Dim, these can be changed with an RF remote or by switching the light switch on and off.
They've worked fine for a few years now without any hassles, but recently the kitchen light & one of the above have developed a 4th setting (standby), so you switch them on and off to cycle through the settings and instead of switching back to Bright from Dim the led's give a slight flicker and then it goes into standby mode, you can use the remote at this point to switch them on etc, but requires an additional click of the switch to cycle back to Bright from Dim.
I've tried new controllers, tried switching over existing controllers from other lights that are not affected by this issue and new switches tna.
I thought it might have been something to do with the power input but it makes little sense 'cos the lights affected are the 1st & last on the feed, with 2 more between them working fine.

The two affected lights have different manufacturers controllers & number of led strips, one being a Single output 30-60w (5 led strips) and the other being a dual output 50-80w x2 (5 led strips per output).
I have just purchased a new dual controller to see if that makes any difference but it'll take awhile to arrive.

Has anyone else come across this issue or have any ideas what may be causing it.

Yes my landlord is aware they have been fitted, he had his own electrical engineer check the installations.
The first batch I received as shown in the pics weren't CE certified (whilst we were members of the EU), so I had to send them back and have them exchanged for ones that were, that was the only issue the electrician had with them.

Nope never had an EICR, didn't know what one was until you mentioned it.
 
Are you saying an 'electrical engineer' has checked those fittings after you had fitted them.

Yup, I originally only fitted one, and asked him to come take a look before I fitted the rest (the one you see in the pic), he noted that they're not CE certified and would invalidate the landlords insurance so I sent them back and got them replaced for ones that were CE certified.
Then I fitted them all and had him check them (my landlord has gone through 4 different electricians in the 8 years I've lived here, he also owns the caravan site & pub next door, so they do the sites electric checks too).
The upstairs lighting loop is earthed, but the downstairs isn't.
I've also pointed out all the bare copper showing from rats gnawing at the cables in the loft space, they just handed me some tape.

As for dangerous the entire of our house was running through a 60a cable back at the main board which is located in the building next door until it melted (our feed comes from the caravan site).
 
You need to remove those fittings. A fault will most likely result in someone getting hurt.
