What’s a Lux?

The ambient light sensor measures light in lux, a measure of illumination that depends on the amount of incoming light and the area over which it is spread.

​

A full moon provides about 1 lux of illumination, a typical lamp-lit living room about 50 lux, classroom lighting and sunrise and sunset about 400 lux, daylight (indirect sun) over 10,000 lux, and direct sun over 30,000 lux.

​

Lux is an unfamiliar unit for most of us. When we buy lightbulbs, we often shop by watts—but the wattage of a bulb doesn’t tell you how bright a bulb is, only how much energy it uses. Lumens are a better measure for light shopping; they tell you how much light a bulb will actually produce. Lux, meanwhile, tells you how much of that light arrives at a particular area.

Questions to Explore (7-10 minutes)

  • How do artificial light sources compare to natural light from a window?
  • What happens near a wall, under a table?
  • Where do you find the lowest reading?
  • Where do you find the highest reading?
  • What happens if you place the light sensor at different angles to the light source? Does tilting the phone make a difference?
  • If you’re outside, explore the natural light from the sun and the different shadows it creates.
  • Which lighting conditions take the best selfie?
  • Which one is brighter? (Test examples)
