Grimmer Dimmer

[pauleras]

Hi Everyone, Ive recently installed dimmer switches in a club which has philips led (dimmable) lamps installed.Philips say there compatible with all dimmers.

Ive got four circuits of lights each circuit has 17 lights with 7w lamps, im using trailing edge 0-400w dimmers. but for some strange reason circuit three seems to flicker at certain points when dimming, you can also hear ticking at the circuit breaker at the Db Board.Ive tried swapping dimmers and lamps etc.

Any advice would be appreciated

Sounds like the dimmer is faulty , check with another dimmer , i know youve already changed , but try again its not an RPP dimmer ive had loads of problems with them.

Are these mains voltage LED's or via a driver?

these are mains voltage LED'S (GU 10).Its Weird as there is four different groups and its only one that starts flickering at certain points about 3/4 of the way.If I turn them all up full and then turn one of the other dimmers down a bit the same set of lights flicker at a certain point.

if you've already tried swapping out the dimmers themselves then it seems like there is some difference in the way this circuit is wired. Are the connections made the same way round at each light? Does circuit 3 run near any data processing lines, or any other source of potential interference (thinking maybe frequency dependent interference here)?
