I bought Sofirn SP33S, because I was interested, if it truly could put out over 5000 lumens from XHP70.2 with boost driver.
Disassembly was easy, little glue on driver, nothing else.
I measured current to led with UNI-T 210E clamp meter and got 5.7A. Pretty impressive.
I then added additional 30mOhm resistor parallel with original 10mOhm one and output rose to 7,5 amps.
Seems like very powerful driver. That’s all for now.
