    Need to rack your brains trying to solve a problem
    A friend bought 3 x 10w leds they are 9-12v 900ma each, Hes bought a 30w led driver specs are 27-45v 1000ma

    Is there anyway he can run the 3 leds off that driver i was thinking in series but not to sure with the voltage, another way would be to find a led buck 30v 900ma but struggling to find one

    any ideas for the lad

    i would think we need to get hold of an 36v 900ma driver to put them in series
