I have 3 10w white LED's , one 3w red and another 3w blue. I want to light up them to their full potential. What is the best way to do that? I just need to turn them on, don't want to control it's brightness. Can't see any circuit to do that. Can I connect it straight to 12v dc in parallel or do I need to add any resistors.

You just need to connect to your power source (12V) with series resistors in line with each LED. Connect each resistor/LED pair in parallel.

You'll need to know the voltage of each LED and the current limit.

Then run the numbers though here:

Remember to calculate power dissipation on the resistor or just use 1W resistors to be safe.
