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). A higher valgusvõimsusega value indicates that a light source produces more light for the same amount of energy consumed, making it more energy-efficient. For example, a 10-watt LED bulb that produces 800 lumens has a valgusvõimsusega of 80 lm/W. In contrast, a traditional 60-watt incandescent bulb that also produces 800 lumens has a valgusvõimsusega of only about 13.3 lm/W.

This metric is crucial for comparing different types of lighting technologies, such as incandescent, fluorescent, and LED bulbs. As energy efficiency becomes increasingly important, understanding and prioritizing high valgusvõimsusega lighting solutions is essential for reducing energy consumption and associated costs. Modern lighting technologies, particularly LEDs, generally exhibit significantly higher valgusvõimsusega compared to older technologies, contributing to their widespread adoption.
