What's wrong with the lamp connection?
Dear community,
What could be causing only one light to be on here (bulbs are fine)? There was only one brown and one blue cable coming out of the ceiling. In the thing (see photo), I had the choice of whether to connect them to the right or left. I even reconnected it again… but the light still only comes on the left (see yellow spot).
That was the
first lamp that I have assembled and connected and I think I deserve a sense of achievement 😉

In the case of alternating current, this basically makes no difference whether brown and blue are exchanged or not. Nevertheless, the lamp should be connected correctly.
Possibly there is behind the white cover of dangerous bast plug.
Don’t do it yourself, but let the expert look. This is intended to prepare the lamp connection to such an extent that all three wires are present and correctly occupied, so that future connection of luminaires is easily possible.
If the pears are in order, the busbar itself is the problem. It is plugged together and thus the connections are ground; the assumption is therefore obvious that the part of the rail on which the non-working lamps are suspended does not receive any current.
Apart from that, there must be a protective conductor in the ceiling (see answer from @Franky12345678).
Unfortunately, it is not exactly visible on photo.
I take the yellow in the middle is the earthing.
And the feeding is black blue. right.
And then the bridge brown and blue to the other side.
So with a measuring instrument you could measure where the voltage is applied and where not…
Look good, so the lamp.
I can’t see the connection on the picture. Too bad. You have to check.
Did you push the unworking lamps on the rail a little back and forth? They will have a grading contact on the rail and if the bite is oxidized or dirty, it will no longer work. Sliding could make it better.
You probably won’t have put them together right somewhere.
Again, and again.
