    I have looked a few places and have found answers but not answers I can understand.

    What I am trying to do is run 10 3 Watt White Luxeon Star LXHL-LW3C LED's from a 12volt car or deep cycle marine battery. They will be in a water tight strip, using them for lobstering hanging off the side of a boat.

    What do I need? Wire in a series or parrallel? Do I have to use a driver? resistors?

    hopefully I have provided enough information.

    Sorry to be so green.

    Thanks for any help

    I bought one to play with.
    They are seriously bright, be careful.
    I had a 5V regulated circuit, a 2KOhm resistor, and the LED lit still almost enough to be painful.

    Maths/phys being a bit fuzzy today....
    P=iv
    V=IR
    I=V/R

    P=V(V/R)

    P=25/2000=0.0125 W??
