SW and Mitras placement

[NorwayEagle]

In the meantime awaiting a confirmation from GHL about compatability between the Control Center SW and Windows 7 Starter, I have installed the lamps, borrowed a Win 7 laptop, and made a Light Composer file.

The lamps looks great over my tank, and I am convinced that 2 lamps is more than sufficient to cover my needs. Very satisfied so far.

I have however one small concern. It is not clear to me how I can make a light profile that completly turn of all LEDs. I would like to have some hours during night without any light.
At the moment I think it is the royalblue LEDs that are on even if all channels are set to 0 %.

Any idea to solve this is highly appreciated.
