Good Morning!
I just got a flashlight with a Cree XHP 70.2 chip (someon confirm me if the chip is not fake) and since I am very maniacal and I like to trick everything, I have had some questions.
1- If I paint the interior area where the LED is allocated with a paint that has a reflective effect or something, like aluminum foil, and that this paint acts as a reflector, would it increase the output lumens a little?
2- In the photos of the driver that I attach below, how could I modify it to further increase the output current? Because in my opinion this driver does not take full advantage of the LED. An observation that I have noticed is that the 4 SMD resistors that seem to be in parallel (R750) are the ones that get the hottest in the entire circuit and already have a roasted whole:faint:
Is it normal for them to get so hot? My theory is that the autonomy could be much higher because these resistors consume part of the circuit current, correct me if I'm wrong

Thank you very much to all!


PS: I upload the photos in drive:
