Problem LED lighting

[Tom@tte]

Hi guys,
I'm hoping there'll be someone out there that could help me on a problem thats occurring with some LED lighting I've installed...
I recently re-wired a large premises of which I installed 4 main lighting mains due to the size of the property.
The problem I'm getting denotes only to the kitchen, dinning room and entrance hallway lighting which is nearest to the new fuse board.
There are 36 no JCC 7w LED recessed lights running throughout the 3 rooms in total switched by Zano LED grid switch dimmers. The maximum on one dimmer is 8 recessed lights (56w) and the mains are switch fed by 1.0 PVC t+e.
The problem I'm getting is that the lights flicker either constantly or slightly all of the time (obviously worse at night)even with the dimmers not being touched. If you adjust the dimmers on any of the circuit then you also get lights beginning to flicker in the opposite rooms?
Ive been in touch with Zano and JCC who both blame each other, one blaming the lights for having the driver on top of the fitting and the other saying it's because of the dimmers creating noise on the circuit?
I've been in touch with a helpful technician at surge protection who advised to fit a surge arrester with built in high frequency filter... My trouble though also is where to fit this and how many would I need as at £110 a pop they're not cheap.
any advice or solutions from you guys would be greatly received as this is really starting to do my head in now


cheers guys


Tom

i'd start with a snubber or two. across S/L and N of the affected circuit. snubbers are only a couple of quid apiece.

Thanks for your reply could you explain what u mean by snubber? Haven't come across this before

Cheers

I take it the LED lamps are dimmable? Also does the dimmer have a minimum load?

snubber is usually a small encapsulater R/C network. filters out transients and induced voltages. try googling snubber ( electrical)

Yes the lamps are enclosed dimmable units and the dimmers have a minimum load of 11w max 60w

is 2 way switching involved anywhere on the LED circuit?

will get searching now. Thanks for the advice telectrix

Yes there are 4 2way switches fitted in total but no more than one per dimmer

It is induced voltage causing the flickers. It is common where you have long cables runs and 2 way switching. With filament lamps, you'd never notice them flickering, as the element would only heat up a fraction to disperse the energy, but CFL's and LED lamps have circuits inside them which will cause the lamps to flicker.

Thanks Alan, would this also be affected by the dimmers being inline?
I've done a bit of research and danlers do an inline filter would you say something like this would help prevent the flickering? How would you go about rectifying it yourself?

cheers

You've been given good advice above, try a snubber.

Ok thanks for your advice
