on a dimmer?

 

[markco]

Nope all on switches and one way

What make are the lamps?

 

[markco]

Crompton 5watt daylights ive put them into front room and there are fine so it cant be lamps

Are all the lamps Crompton and is the problem just in the dinning room ? I have been called to a job once where some cheaper GU10 LED lamps flickered/part lit when turned off changed the lamps and all was ok.It might be faulty electronics in one of the lamps.

Sounds like a loose connection just before the dining room; the connection can carry a small current but a larger current causes it to fail, briefly.
However the currents should be so small it hardly makes a difference, so maybe it is just the switch not quite making contact.
Normally I would be thinking overloaded transformers but this fails for GU10s!

I had a case where one gu10 led was faulty, although it lit and appeared fine on the face of it, whenever it was on it made all the other lamps on the circuit flicker. It was a bit of a headscratcher at the time.

how are the others wired ? did you splice into a cable see a blue and brown wire assume its live and neutral add junction box and bobs your uncle , it could have been switch wire, you need to test for voltage , i have seen this is the flesh

Yes lamps are crompton and yes problem only in dining area and only flash when switched on

Its a brand new circuit i put in and no i didnt splice into a cable the rest of the rooms work fine just dining room works ok with 1 led but as soon as u add another one there flash only when switched on

 

[Oliver Townsend]

have you tested the voltage at each light ?

 

[Oliver Townsend]

i didnt mean to offend its just ive seen a home owner do that exact thing and im unaware if there are builders , homeowners etc posting

Try swopping the 6 LED lamps between the kitchen and dinning room if the dinningroom is then ok and the problem transfers to kitchen may prove one of the lamps.

May be induced voltages in the wiring. Try putting one of these across the lamps
