Trailing edge dimmer interference

[Welshsparky]

Have installed 11 led downlighters to be controlled by a trailing edge dimmer switch , Inbetween the downlighters are some 0.5 watt led lights which are separately switched , when the smaller led lights are switched off the led downlighters turn dim for around a second then go back to full brightness , is the dimmer switch picking up some sort of interference ?

Thanks

It's possible the dimmer and the LED driver are interfering with each other. What type of dimmer is it ie is it 4-wire tactile with a bell pres, rotary, touch control, remote control etc?

If the neutrals are all in the switch you could try installing a double pole switch for the small LED's. Not guaranteeing it will sort it out but it might rule out a few things.

It's just a start rotary dimmer switch in white plastic , all neutrals are up at the lights , would it be worth shopping the dimmer for a different brand ?

Standard rotary **

Which dimmer switches do the LED light manufacturers recommend?

What's the minimum required load for the rotary dimmer? Do your LED downlights add up to more than this figure? Dimmers become unstable if there's insufficient load.
