what kind of voltage for IF25A head

Hello

I’m building a light for my mill machine and i have a faulty sofirn if25a (faulty driver). So i want to know how to drive the LEDs
There are in parallel (2 red positive wires) and i assume that the 2 6500 and the 2 2700 are in series ?

So i need 3.8X2= 7.6V for each red wire ?

Like my old build of MTG2 @6V i feed a DC to DC PWM driver so i can choose the intensity.





my old build for the other machine




The LEDs should be in parallel as the original FET+1 driver runs on a single battery. If you want to control the two channels individually, you could run two LEDs in parallel, but it should also work fine to run all four in parallel.

The driver should be able to deliver up to 3.8V depending on how hard you want to drive it. The exact voltage does not matter, because your driver will be current regulated anyway. 8A in total should be fine with good cooling.

ok thanks you !
i’ll get a 5V 10amp power supply and a dc to dc converter
