A Lux Meter is a device used to measure the intensity of light in a given area. It quantifies illumination in units called lux, which indicates how much light is received on a surface. This tool is commonly used in various fields, including photography, horticulture, and workplace safety, to ensure adequate lighting conditions. The readings from a Lux Meter help users determine if the lighting is suitable for specific tasks or environments. For example, in a photography studio, proper lighting is crucial for capturing high-quality images, while in a workplace, sufficient illumination is essential for employee productivity and safety.
