Clarification - Space shuttle lighting?

Question

When a space shuttle is in outer space, are the lights inside the actual shuttle from the sun, like daylight, or are they artificial lights?

Answer 1

Hi. The shuttle has some windows but, because it travels from day to night every 90 minutes or so, they use artificial lighting.

Answer 2

There are electric lights in the shuttle, but sunlight streams in the windows too, when the Shuttle is on the daylight side of the Earth.

Answer 3

The shuttle has lights for use when it's on the dark side o fthe planet.
