Unit Explanations
Luxlx
Source UnitThe lux (symbol: lx) is the SI unit of illuminance and luminous emittance, defined as one lumen per square meter. This unit quantifies the amount of visible light that illuminates a surface area, providing an essential measure for lighting design and assessment. The lux is integral to various fields, including photography, cinematography, and interior design, as it helps determine the adequacy of lighting in spaces. A well-lit environment typically requires illuminance levels ranging from 100 to 1000 lux, depending on the activity being performed. Thus, the lux not only conveys the intensity of light but also directly correlates with human visual comfort and productivity.
Current Use
The lux is widely used in various industries to ensure that lighting conditions meet specific standards for safety, comfort, and productivity. In architectural lighting design, lux levels are meticulously calculated to optimize illumination in spaces such as offices, schools, and hospitals. The film and photography industries rely on lux measurements to ensure proper lighting conditions for shoots, while horticulture utilizes lux for assessing light requirements for plant growth. In the automotive industry, lux is crucial for assessing headlight brightness and visibility. Countries around the world, including the United States, Germany, and Japan, apply lux standards in building codes and regulations to ensure adequate lighting in public and private spaces. Regulatory bodies often specify minimum lux levels for various environments, ensuring compliance with safety and quality standards.
Fun Fact
The human eye can perceive light levels ranging from about 0.1 lux (moonlight) to over 100,000 lux (bright sunlight).
Noxnx
Target UnitThe nox (symbol: nx) is a unit of illuminance that quantifies the amount of luminous flux received per unit area. It is defined as one lumen per square meter. This unit is essential in understanding how much light is present in a given space, influencing studies in photography, architecture, and environmental science. The nox provides an understanding of visual comfort and safety in both indoor and outdoor environments. In practical terms, it plays a critical role in designing lighting systems for residential, commercial, and industrial applications, ensuring adequate illumination for various tasks and activities. The nox is a vital parameter in evaluating light pollution, energy efficiency, and the effectiveness of lighting sources.
Current Use
The nox is widely used in various industries, including architecture, photography, horticulture, and environmental science, to evaluate and design lighting systems. In architecture, it helps in creating comfortable and functional spaces by determining the appropriate light levels required for different activities. Photographers utilize the nox to assess lighting conditions for optimal exposure settings. In horticulture, it plays a crucial role in ensuring adequate light for plant growth, particularly in controlled environments like greenhouses. Countries such as the United States, Germany, and Japan have incorporated the nox into building codes and safety regulations, emphasizing its importance in public safety and energy efficiency. The nox is also used in research studies examining light pollution in urban areas, contributing to environmental sustainability initiatives.
Fun Fact
The nox is essential for assessing light pollution in urban environments.

Lux
illumination • SI Unit
Definition
The lux (symbol: lx) is the SI unit of illuminance and luminous emittance, defined as one lumen per square meter. This unit quantifies the amount of visible light that illuminates a surface area, providing an essential measure for lighting design and assessment. The lux is integral to various fields, including photography, cinematography, and interior design, as it helps determine the adequacy of lighting in spaces. A well-lit environment typically requires illuminance levels ranging from 100 to 1000 lux, depending on the activity being performed. Thus, the lux not only conveys the intensity of light but also directly correlates with human visual comfort and productivity.
History & Origin
The concept of measuring light dates back to ancient civilizations, but the formal introduction of the lux occurred in the 20th century. The unit was officially defined in 1948 during the International Conference on Weights and Measures in Paris, where it was adopted as part of the International System of Units (SI). Before the lux, illuminance was often measured using different units like foot-candles, which were less standardized. The establishment of the lux aimed to create a uniform measurement standard for scientific and practical applications in lighting.
Etymology: The term 'lux' comes from the Latin word for 'light'.
