Light meters measure light levels or light pollution within the environment. It’s a key piece of equipment to ensure that there is the right amount of ambient light within the workplace, at school or even at home, and are often used by photographers in studios and natural environments to calibrate film equipment. They most often measure light sources like white LED light, fluorescent lighting, metal halide, high-pressure sodium and incandescent lighting. The most common types of environments where light meters are used are:

• Warehouses and factories
• Commercial office buildings
• Hotels and restaurants
• Public buildings
• Schools and other educational buildings
• Libraries
• Museums and art galleries
• Hospitals and other healthcare buildings
• Garages and car parks
• Stadiums and sports & leisure buildings
• Building commissioning, operation and maintenance
• Building security
• Photography and video
