The test time is 2035 july 6 02:00 its dark and boat lights are visible till. 2:45 when the light is fadeing, but its still dark outside. The darknes fade at 3:10. The surrondings are seenable at 3:15. At 4:00 the golden sun shine on water can be seenable, but the sun siluets only seenable at 4:15 on the horrizon. So the light system need some little tweaks. (anyway all these things looks gorgeous)
