Just to get your feet wet with leds, I'd recommend using only 4-6 Cree XP-G's, a Meanwell LDD driver ( accepts 5V PWM signal directly from Arduino) a modest heat sink and a 24V/2A "Walwart" or Laptop style power supply. The leds can purchased in either cool or warm white, so you can mix the ratio to your liking.
You can find the LDD-1000H right here-LDD-1000H | Mean-Well LDD-1000H | USA Warehouse
FleaBay for the power supply & LEDGroupBuy for the leds and heat sink.
