It has the words Electronic Transformer printed on the case.
Any three? Even the three that are supposed to be 2W each?
Yes. I tried various combinations. It's very odd.
The three 5.3w Omlopp lights will work fine together, as soon as I add one 2w Lindshult to it the on/off flashing starts. then vice versa, the three 2w will work fine, but I cannot add a 5.3w to it.
I see what you are saying, 15.9w versus 6w, in theory I should be able to get at least 4 lights on, 3 x 2w and 1 x 5.3w. Or a combination of.
In addition to that I should also say that although they switched on immediately when 1st checked. About an hour later when I went into the room again I turned on the switch at the wall and the 3 lights initially flickered before eventually coming on permanently.
Thanks

Can you honestly say that nothing is ever wrongly marked?
I know for a fact that all too often the written ( and posted ) words are factually incorrect.
Are all three neutrals joined together? Your picture makes it look as if the neutral to the main light is not connected to anything.
Nothing wrong with the supply to the LED though, if the other wires do what you think they do.

A reasonable good quality currnet source ( switch mode ) LED driver was connected to the output of the "12 volt DC" unbranded " electronic transformer.
The wave form of the "12 volt DC" became very erratic with many high frequency components , measuring via a low pass filter displayed a predominate frequency that varied between 300 and 500 Hz Possibly the beat note between the 1.7 kHz of the supply and the operating frequency of the LED driver.
The power supply was getting hot so the tests nave been stopped.

No, to be fair the neutrals are not joined together, but the main light bulb is working fine. Only the mains neutral and LED neutral are in the same terminal. I can change that.
When you say, "if the other wires do what you think they do", can you please explain? The transformer only has live and neutral and they connect to the light switch (above) via a junction box, live to live and neutral to neutral. So it is a like for like linkage.
As regards the lighting circuit (mains wire to breaker) it is per the picture above and feeds into the lighting circuit loop as per normal.
Excuse my ignorance but not sure what you mean?
Thanks
It shouldn't be working if its neutral is not connected to anything.
The fact that it is working suggests that it is not actually wired as you've described.
How do you know that the cables you've described as "to mains" and "to main light bulb" do go there?
Hi Bernard,
Can you say more about this current source? E.g. photo or link or something?
The wiring to the switch is exactly as described.
The wiring to the main light bulb is old, which is perhaps where your doubt is. But it does work as described. We could not re-wire the main bulb due to access to that wiring. Instead we linked it via another junction box from old light switch (now boxed in and isolated), again like for like. But to be honest that is not relevant to the LED set-up, which is the issue of this thread.
The mains lighting circuit loop is as described because that is 'new'. It is a spur from the lighting circuit. Which is new wiring set up (certified under building regs when we did extension)
So in conclusion we have new wiring running from switch to mains lighting circuit (spur). We then have new wiring going to the LED transformer via a junction box. Lastly we have new wiring going to junction box for main light bulb, joining old wiring set up.
Any advice appreciated. But I suspect I just need a new transformer.
