Supply side hooked to your 12V rail, output side powering your LEDs. They come in a variety of constant current levels, 300mA, 350mA 1000mA etc.
Then you connect the PWM wire to a PWM output pin of an Arduino, and control it with either Michael or Greigs plugin.
This is how I'm doing the lighting in my home now. I use the LDD-H board mount variants supplied by a 48V DC PSU, powering BridgeLux Vero 10 COBs in the downlights. Concept is exactly the same just with different voltages.
Edit:
Alternatively, the Qubino RGBW Z-Wave module can be configured to control 4 x 12/24V lights independently. And it only requires a 12/24 VDC supply.
