Valgusvõimsusega
Valgusvõimsusega, often translated as "lumen power" or "light efficacy," is a term used to describe the efficiency of a light source. It quantifies how effectively electrical energy is converted into visible light. The standard unit for measuring luminous flux, which represents the total amount of visible light emitted by a source, is the lumen (lm). Power, typically measured in watts (W), represents the rate at which energy is consumed.
Valgusvõimsusega is calculated by dividing the luminous flux (in lumens) by the power consumption (in watts).
This metric is crucial for comparing different types of lighting technologies, such as incandescent, fluorescent, and
