Lighting Problems since switching to digital ballast

[Nabzter]

So I went to check on my girls today and the lights were out .
I then with obvious concern tried to find the problem. I tried everything possible even a brand new build of the same brand as the ballast (lumii). I tried running different bulbs at different wattages as it is a dimmable. It appeared the ballast was not allowing the required amount of energy to the bulb and I was just getting the odd flicker of light. In the end just gave up and switched back to good ole trust worthy magnetic.

Please help !!! Any ideas.
