need an expert opinion on this connection

It's fine as it is. According to a web search, each of your 19-LED clusters is rated at about 1.4W. The driver you have is rated at 5W, so the load is well within its rating. It's the correct voltage driver for the cluster, so there is no danger of overdriving the LEDs.

Makes me wonder again about why the halogen transformer was used - the LED driver could have coped with the load of all three lamp clusters (4.2W in total) but at least you have some redundancy in using two drivers split across 1 and 2 clusters each.

To be honest everything else in the house seems to be connected correctly (says me that knows how to change a bulb not much else). I did some reading about the halogen and I am still wondering that also. it is possible that the previous owner did his own dyi I guess. I dont see the electrician that installed the switch and the lights making that mistake; but then again, there are cowboys out there.

Hi, i would test each lamp individually using the LED driver then check if all is working 100%. Then connecting one lamp at a time and check its operation, if its all good connect the second and third accordingly. As stated above driver has capacity to run all 3, just ensure polarity is correct.

Hi Garethly, I actually did that using the driver that is on the picture. the one that lit up properly alone, then switched to each of them at a time before adding the new led driver into the mix. Thank you though
