Hey there,
I'm building a quad arial drone and the frame came with four leds, one on each of the four arms. There are two white leds and two red leds, and I want to make them last, as they're really cool looking. They will be powered by 12v from a power distribution board,which is powered by a 4S 10,000 Mah LiPo battery The leds themselves are connected by 22ga wire from the factory. I will add one resistor to each positive wire and then connect them all to the PDB, keeping positive to positive and negative to negative. What size resistors should I use for medium, but long term brightness?

Thanks Joe

 

If I am not asking the question correctly/clearly, please let me know.

Thanks, Joe

Brightness is a subjective term. Without knowing the specs for the LEDs, and what you mean by medium and long term brightness; no meaningful suggestions can be given.
