1 x black in l1
and the red wire has not been cut and is one complete cable
any ideas

Is it a compatible dimmer (LED), wattage, leading/lagging etc with the lamps/drivers you've got. Are the lamps dimmable?
Are the lights connected properly , polarity, (Including the cpc [earth wire])?
If all ok possibly faulty dimmer module.

its not a dimmable switch but the led's are dimmable its a simple on and off switch tried a few switches all the same all i have done is wire what was in the rose to the l e n onthe downlight and the other len is a cable to the next downlight. i thought maybe the black wire that comes from l1 was in the wrong l e n so i switched the l n but the outcome was still the same

Doubt the problem is with the switch then. Are they 230v units (ie integral driver)? Are they all terminated correctly?

ok thanks I will try that

its a double switch one is for outside light

If it's an old house the lighting circuit can pick up unwanted "capacitance" if the light circuit cables run near to other power cables. Watch the first 5 minutes of David Slavery's video on nuisance glowing LEDs

I fitted 4 of these in the bathroom on existing wiring and they do exactly that.
Fitted 14 in the kitchen, new wiring, no problem.
Havent got round to trying a snubber yet, or replacing the wiring.

You've shown a picture of the light fitting and the switch, can you also show a photo of the dimmer please.

I don't think there is a dimmer, Marvo. It's just the lights are dimmable variety.

This suggests that the supply cable comes via the switch and that switch is in the neutral. Apart from safety implications, switching the neutral could give the effect described due to stray capacitance. How many cables were at the original rose?
