Random downlight flickering

[Tom edison]

Hi
Ive never seen this issue in 35years in the trade and wondered if anybody has any idears.
The property is a new build and the installation fitted by myself. We have 26 Aurora cx7 downlights on 3 seperate circuits and controlled by various switching configurations. All dimmer switches are Varilight V- pro modules and the consumer unit is the new Click Elusian split load board with SPD.
The lights flickers very randomly sometimes not for a day or 2. I have checked everthing. No loose connections. Aurora have sent new fittings which i have fitted. I've changed the dimmer modules but the problem is still there. Has anyone got any idear what this could be or has any body seen this before? I've now hit a wall as to where to look next.
Thanks

I have LED lights in near every room at home all on Vpro dimmers and for most part all function fine.
However every now and then the flicker or fade for a second before returning to normal.
Like you have tried various makes of lamps and switched around modules but it still happens from time to time.
I have learned to live with it as a quirk

Ive had the same with different combinations of vpro and light brands. Try different dimmers, maybe zano, varilight also do the vcom which may behave different

The ads on this site are ridiculous. So difficult to read or answer anything. Ive tried all the above solutions with no luck

Take a look at the reference and the section called 'Overview' at the link above. It explains how to change between one of three modes of sine wave switching. The default setting is Mode 1 - trailing edge but there is an alternative trailing edge mode - Mode 3. You could also try Mode 2 which is leading edge.

Is the dimmer getting overly warm? Subjective I know . You could try it with the face plate adrift from the wall by a few mm to see if the increased convection air flow improves matters.

What csa have you wired the circuits in - the new 0.5mm2 T/E ?

I'm aware of the dimmer modes and have tried all of them. Thing is ghe lights on a standard rocker also havd the problem so its not the dimmers

I will have another think. Do your neighbours with LED lighting experience the same problem? You will need to ask at several homes to cover all three phases.

And a temperature factor?
