Emisar D4, RGB + White:
The 5 channel full ramping driver (FET+1 for white, red+green+blue) with 2 additional resistors for ultra low white moonlight and red indicator light, color channels pretty overdriven for about 1.5 Amps at each color XP-E2 (NOT recommended though):
Very nice beam:
Even nicer rosy beam with all LEDs on max current, about 1500 lumen (white LED is XP-G2):
