I've been doing a bit of research on the subject of LEDs. But aren't these filament LEDs? Because COB LEDs are essentially LED strips, the LED density is higher, and there are many micro LEDs and there is a silicone layer on them. It might be better to use a series resistor instead of a voltage regulator because the voltage regulator makes EM noise imo... The only disadvantage with resistor is that a resistor is slightly less energy efficient and you would always have to use the same battery. Because it is tuned exactly to an input voltage...

Another disadvantage of series resistors is of course that the luminosity of the LEDs decreases when the battery voltage drops from 4.2 to 3.2 V...

Thanks for the info and insight. I'll look into these LEDs more about whether they are CPb or filament. I don't produce these - just reselling them. They do indeed get duller as the battery voltage decreases.
