What are light levels?

Light levels tell us how bright or dim it is around us, like counting how many tiny sunbeams are shining on your face at the same time.

Imagine you're playing with a flashlight in a dark room. When you turn it on, the room gets brighter. That’s because more light is coming from the flashlight to your eyes. Now picture this: if you’re outside on a sunny day, there are a lot of sunbeams, that’s a high light level. But if it's nighttime and only a few stars are shining, that’s like having just a few tiny sunbeams, a low light level.

Think of light levels as the number of flashlight beams your eyes receive from all directions at once. A sunny day might feel like 100 flashlights shining on you, that's a high light level! Inside a dark room with just one flashlight, it feels like only one beam is reaching you, that’s a low light level.

So next time you're playing hide and seek, remember: the more light there is, the easier it is to see your friends hiding! Light levels tell us how bright or dim it is around us, like counting how many tiny sunbeams are shining on your face at the same time.
