I feel like it's not directly comparable because light gets reflected around indoors. I imagine having full sunlight indoors would turn everything white.

- jdietrich 3y agoIlluminance (lux) is a measure of the amount of light falling on a surface, not the amount of light being emitted. Any reflected light will count towards the measured illuminance. Sunlight is just incredibly bright. There's a reason why film crews often need to use huge metal halide lamps powered by a generator truck - it takes an immense amount of power to compete with daylight. https://en.wikipedia.org/wiki/Illuminance https://en.wikipedia.org/wiki/Illuminance https://www.arri.com/en/lighting/daylight/arri-daylight-18-12 https://www.arri.com/en/lighting/daylight/arri-daylight-18-1...
