light measurement

Light measurement involves quantifying the brightness or intensity of light in a given environment. Tools like light meters are used to assess how much light is present, often expressed in units called lux or foot-candles. Lux measures illumination as perceived by the human eye, considering how bright a surface appears, while foot-candles measure light in feet-based units. Proper light measurement ensures spaces are adequately lit for comfort, productivity, and safety, and helps in designing lighting systems that are energy-efficient and suitable for specific activities.
