As far as I am aware, the buck pucks dim 0%, 1%-100%. I don't think there is actually a driver that can do truly 0% to 100% but the buckpuck was the closest I could find to the full dimming range. Most drivers only come on at 10% and up (1-10V dimming = 10%-100%).
Instead of running moonlighting, I'm just going to have my blues stay on at night around 5% or so. The nice thing about the Typhon controller is that it is easy to re-program to have features such as the moonlighting, etc.
The Typhon is arduino based. You don't need A to PWM conversion if you're running an arduino. It has PWM output which a number of driver can take.
