    Hi all,
    Just wondering if anybody knows the volts and mw the red leds on the p3 arms put out,
    I want to tap into the poss and ground ,red and black wires and add more leds on the body
    of the p3. or wondering if I can add a relay switch to them so I can turn on and off all leds
    from the radio, also if I put black tape over the green lights, i'll be able to fly in total darkness.
    then slide the lights on and off at any time.
    thanks guys, Kevin

    You can turn the front red led on and off from the dji go app.

    Here's the setting in the DJI Go App for turning the red lights off.

    Interesting project. What kind of LEDs are you planning to put on your P3?

    Yes, I know how to turn on and off the leds from the app,... the problem is I need to
    know the voltage and amps that the actual led are using,the leds I want to use are
    12 volts and use 680mw (.68 amps) .
    so I need to know that information, before I proceed any further with this project.
    thanks ,kevin

    Whats really important is what is the capacity of the driver circuits (transistor, etc) the LEDs have.

    For economic reasons the circuits are typically designed for what is needed and there was no anticipation by DJI of the user adding additional loads and thus adding additional capacity.

    Without knowing that you are just taking chances.

    Not clear on your specs. but if it is .68 amps that's a lot of current and you will fry the drivers.

    Amps and Watts are not the same. Watts are Amps times the volts. ( W= A x V)
    Therefore the amps can be determined by:
    Amps=Watts/ Volts

    So.. was it ever determined at what voltage the leds are driven? Maybe someone who opened their phantom today can do a quick measure?
