Lights and Effects

Led floodlight illuminates almost nothing!

Hello guys, good morning, I tell you, I have a 50W led reflector, but from one day to the next I stop working and it shines very little, I see that the LEDs light up but maybe one more alum match. The reflector is relatively new for a couple of months and will have been used for only a couple of hours. When disassembling it, note that it is composed of two parts. 1 are the LEDs and the other is a kind of transformer. I wanted to know how I can identify which of the two fails so replacement. Thank you very much attached image!

The fault is the DRIVER LED that looks like a transformer. It must deliver between 65V and 90V. To be used in different quantities of LED.

Hello ennio excuse me but here is so much assurance that there is the fault? LEDs are unlikely to fail? Do you have to buy the LED driver again? Thank you

LEDs can fail in 2 ways. If an LED burns and the circuit opens, it does not light any. And if one of the LEDs is shorted, a black dot would be seen and the rest would shine more.
As they all turn on, it is the DRIVER LED.
Measure the voltage you deliver.
You can open and repair it if you have experience.
On Aliexpress you can import it at a lower value.
