The history of Candela goes back 150 years. The difference between lux and lumens by definition The core difference can be summarized as follows: Lux is a measure of illuminance, the total amount of light that falls on a surface; Lumens is a measure of luminous flux, the total amount of light emitted in all directions. Lumens measure luminous flux, which is the total amount of light a light source produces per unit of time. Lumen (lm) is the SI-based unit that measures luminous flux, in other words the total amount of light produced by a light source per unit of time. Candela is light’s intensity as visible to the human eye in a specific direction..
