I thought to use an AC/DC 12V 60W converter to power them all and place the right resistor for every series of LEDs (2 LEDs in series of the same colour, all in parallel) and switch them using Mosfet IRF 540N
I've found this guide.http://www.instructables.com/id/Circuits-for-using-High-Power-LED-s/?ALLSTEPS6th step seems to be quite simple and cheap to build.
i was thinking about using IRF540N, but someone told me that ann IRL would be better. Any advice about it?
As far as I know, also the N in IRF540N means that the mosfet can be turned on with arduino's 5v
Talking about mosfets, do they need also a heat sink?
Would they heat?
