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).
Meter Candlemc
Target UnitThe meter candle is a unit of measure for luminous intensity, defined as the intensity of light emitted in a particular direction from a source that radiates uniformly in all directions. It is equivalent to one lumen per steradian. The meter candle is not an SI unit, but it is used in certain contexts within the field of photometry. This unit is specifically relevant when discussing the luminous intensity of light sources, particularly in applications related to lighting design and evaluation. The concept of the meter candle helps standardize measurements of light intensity across different lighting conditions, ensuring consistency in studies and applications involving illumination.
Current Use
Today, the meter candle is primarily used in fields that require precise lighting measurements, such as architectural lighting design, photography, and theater production. While it is not a commonly used unit in everyday applications, it finds relevance in professional environments where accurate illumination levels are key to achieving desired visual effects. The meter candle is employed by lighting designers to assess how light interacts with various surfaces and materials, ensuring optimal visibility and aesthetic appeal. In countries like the United States and several European nations, the meter candle is referenced in professional lighting standards, guidelines, and regulations to promote safety and quality in lighting installations.
Fun Fact
The meter candle was once defined based on a standard candle made from a specific type of wax.

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'.

The concept of the meter candle helps standardize measurements of light intensity across different lighting conditions, ensuring consistency in studies and applications involving illumination.
History & Origin
The concept of measuring light intensity has been around since the early 19th century, with significant contributions from scientists such as Sir Humphry Davy and later from the International Commission on Illumination (CIE). The meter candle was introduced to provide a standardized measure that could be utilized in various practical applications, especially in the burgeoning fields of photography and theater lighting. The standardization of light measurement was crucial as industries began to recognize the importance of proper illumination in enhancing visual experiences and safety.
Etymology: The term 'meter candle' combines 'meter,' a fundamental unit of length in the metric system, with 'candle,' derived from the Latin 'candela,' meaning 'to shine.'
