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??
