, does anyone know what the power consumption of the V+ box is, and if you switch it off at the mains when you are away, does it retain all its settings?

Has anyone noticed that when it is in standby, the light is quite powerful. I got up in the middle of the night and I thought I'd forgotten to switch my main lounge light off! It was like daylight down there!
