Lumens Per Square Foot: Measuring Light Intensity

“Lumens per square foot” is a metric used to measure the illuminance of an area. It is the amount of luminous flux (lumens) falling on a surface per unit area (square feet). Higher lumens per square foot indicate brighter lighting conditions, while lower lumens per square foot indicate dimmer lighting conditions. It helps architects and lighting designers determine the appropriate light levels for various spaces such as offices, warehouses, and retail stores to ensure adequate visibility and visual comfort while considering energy efficiency and environmental impact.
