It's also what I thought when I bought the LEDs. But I had a bad surprise to see that it did not work like that. It is also to try to understand that I opened the thread.

This would be true for a power supply with a transformer, but most power supplies are now switched and to stabilize the output voltage, they need a minimum current, otherwise the output voltage increases and, if the power is good done, it is safe (if it is poorly done, it burns the load).

Ah yes, the power supply that I had yet listed, what a donkey.

Thanks for the reply Gaston. At least now I understand why.
