That angular span is a two-dimensional angular range we measure in steradians (sr). Luminous intensity is amount of light emission in a particular angular span. The last photometry quantity on our list is luminous intensity. We can also use lux as its unit of measure, where 1 lux equals 1 lumen per square meter. The illumination that the surface receives is equal to 10 lumens per 2 square meters or 5 lumens per square meter (or lm/m²). Let's say a light source emits a luminous flux of 10 lumens to a surface with an area of 2 square meters. Illuminance (or illumination) is the amount of luminous flux that a particular surface can receive. In this text, we'll also cover illuminance and luminous intensity and their relationship with luminous flux. Other than the luminous flux, we also use other photometry quantities to describe the brightness of a light source. If this is a route that your institution plans to go we will need to whitelist your specific URL.Lumen is a unit of measure for luminous flux, which is the total amount of visible light (within approximately 0.4 to 0.7 µm wavelength) a light source emits.
