Light meters (also known as lux meters or lumen meters) are hand-held digital devices used to measure light intensity or light pollution within a sample or environment.
How is light measured using a light meter?
Light meters measure light by attributing a measurement unit value, either in lux (1 lumen per square meter) or foot candles, and are most commonly used in photography for determining optimum exposure in photographs.
What are light meters used for?
Light meters are frequently used for a wide variety of applications and industries:
- Cinematography and photography: To determine adequate light exposure and scene lighting.
- Agricultural greenhouses & horticulture: For ensuring optimum light for plant and vegetable growth.
- Biological & environmental science: For studying growth patterns of vegetation such as trees, plants and fungi and their impact on the eco-system.
- Busy city districts and streets: As a means of measuring levels of light pollution.
- Theatre and performance: To ensure optimum lighting during performances.
