The proper term for ambient light is ‘illuminance’, the received light that falls on a surface, which we measure in lux. 

Get into the habit of using a meter to measure critical positions in workspaces as it really helps you read a space and understand the huge variations that our eyes can’t pick up (as human perception of light is logarithmic).

I have an Excel worksheet I use for teaching that walks you through all the main measurements, recording them, plus useful calculators. Message or email me and I’ll email you a copy.
