The lux (symbol: lx) is the SI unit of illuminance and luminous emittance, measuring luminous flux per unit area. It is equal to one lumen per square metre. In photometry, this is used as a measure of the intensity, as perceived by the human eye, of light that hits or passes through a surface.

400 lux: Sunrise or sunset on a clear day.
I think this is probably what the title 400 Lux is referring too, I mean the song is about wasting time and it mentions orange juice which you drink in the morning. Either that or I am trying way to hard to make sense of the title.
