Under cabinet LED lights issue

[rustynails]

Hi all,

I have a problem with two sets of 12V LED under cabinet lights. Set 1 is a set of 6 lights under the kitchen cabinets. Set 2 is a set of 4 lights above in glass cabinets. The problem is set 2 flicker/pulse every 20/30 seconds whilst set 1 is on and only when set 1 is on.

I have IR’d the 3 core to the junction box which is ok, checked the wiring arrangement and connected set 2 separately without set 1 connected which works ok. Only when set 1 is on does the problem occur, it’s very strange…

Wiring diagram here

Ideas welcome...

why did you put to l2 on the switches the tails need to be in l1on the switch ?

Drawing error not that it matters too much.

I usually connect the switch wire to L2 when doing a one way, as sometimes I've connected to L1 and the off position on the switch is actually on

Its only a thought and other than thinking possibly induction it is pure guesswork
Try running the lights off switched feeds not in the same cable

That’s a good idea I could try that, might be harder to implement seeing as I’ve just walked in to this new kitchen and didn’t do the work. If I had I would have done seperate feeds.

Not sure what you mean re induction?

Hi bud,what are the type,make,etc of the drivers and LED's?

You have a 300%+ driver for only 50% more lamps,which might not matter,but does depend on what is being used.

Eh? What's going on there then, do you fit switches upside down or something?

try feeding both sets through 1 switch.

Agree with Des something to try, and without knowing how things are installed, make sure the 230v cables are not running alongside or near to 12v wires. Try another switch.
