= Orders of magnitude (illuminance)
{wiki=Orders_of_magnitude_(illuminance)}
Orders of magnitude in the context of illuminance refer to the scale of measurement used to express the intensity of light that reaches a surface. Illuminance is typically measured in lux (lx), where one lux is defined as one lumen per square meter. The concept of orders of magnitude helps to understand the relative difference in illuminance levels, as these measurements can vary widely. An order of magnitude is a factor of ten.
