light output

Light output refers to the amount of visible light produced by a source, such as a lamp or bulb. It is typically measured in lumens, which quantify the brightness perceived by the human eye. Higher lumens mean a brighter light, while lower lumens indicate a softer or dimmer light. Factors like bulb wattage, design, and technology affect light output. Understanding light output helps in choosing the right lighting for different spaces, ensuring enough brightness for activities without excessive energy consumption.
