Optimally; One LED on each side, largest possible angle. As much 'bang for a buck' as possible, meaning that more wattage equals better.
As we basically only have to run 3 or 4 channels (RGB/RGBW, both LEDs run with the same signal, but in different directions) we don't need an on board PWM chip but can rather do PWM ourselves, which allows us to get LEDs with more wattage.
