In our physical comfort zone.<quoted text>
Actually, Saturn ranges in distance from the sun from a bit over 9 AU to a bit over 10 AU. That means the energy intensity there varies from about 1/80 to about 1/100 that on the Earth. Now, direct sunlight has an intensity rating of about 32,000 lux, while daylight (not direct sun) has an intensity of 10-25,000 lux.
If we consider the intensity at Saturn when it is furthest from the sun, we take 1/100 of the intensities here to find about 320 lux for 'direct' sunlight on Saturn and around 100-250 lux for 'daytime' on Saturn.
Now, typical office lighting is about 320-500 lux and 'dark, overcast day' is about 100 lux. Family living room lights are about 50 lux.
The conclusion: the light on Saturn in direct sunlight is about what is found in a typical office (on the dark side of these) and is more than a dark, overcast day on Earth. It is much more than the intensity produced from a typical living room light.
It should be a little brighter adding the luminescence and tiny bit of incandescent light produced by Saturn. If you were a planet orbiting it.
Kind of like a greenhouse.
