xml 10W drivers

[ikaros45]

Hello people,

I'm looking for some help to power my 10W LED. It's supposed to use a current of 3A at 3,7W.

I was recommended to use 4 of these LED drivers in parallel:

DX SKU 66329

This is the result:

Now the problem: light blinks a little. It never fades but intensity of light changes and it's not very pleasent.

If I only use one driver, it works perfect, of course, not too much light. Then when I connect the second one, light starts to blink a little. And so on... with the four drivers it's sparkling a lot.

Is there anything wrong there?

One interesting thing, if I use the multimeter to check what intensity is going through the LED, the light is more stable.

I double checked all the conections... and nothing, it still blinks.

Thanks in advande

Not all drivers can be run in parallel. You need to know what the driver's guts are to see if you can stack 'em.

its better to use single 10W driver. parallel use will fool current limiting circuits of each drivers if there are voltage difference & reverse voltage.
