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).
Centimeter Candlecm·cd
Target UnitThe centimeter candle is a unit of luminous intensity that quantifies light output in terms of a standard candle's intensity at a distance of one centimeter. Specifically, it measures the luminous intensity of a light source emitting light uniformly in all directions. The centimeter candle is defined such that it produces a luminous intensity of one candela when measured at a distance of one centimeter. This unit is particularly significant in fields requiring precise measurements of light and visibility, such as photography, optics, and lighting design. The centimeter candle is not a standard SI unit but serves as a useful metric in specific contexts, particularly in the evaluation of light sources in laboratory settings and specialized applications.
Current Use
The centimeter candle is used primarily in fields that require precise assessment of light intensity. Although it is not commonly used in everyday applications, it has specialized applications in photometry laboratories, optical engineering, and the development of lighting technologies. In these contexts, the centimeter candle serves as a reference point to evaluate the performance of lighting products. Industries such as photography, cinematography, and architectural lighting design utilize it in the calibration of light meters and photometric testing of bulbs and fixtures. Countries that traditionally used the centimeter candle include those with historical ties to traditional lighting technologies, such as France and the United Kingdom. In modern applications, however, the candela has largely supplanted the centimeter candle in most industries, yet the latter remains a point of reference in academic and research settings.
Fun Fact
The centimeter candle was developed during a time when gas lighting was still commonly used, reflecting the transition to electric lighting.

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'.

Centimeter Candle
illumination • Non-SI
Definition
The centimeter candle is a unit of luminous intensity that quantifies light output in terms of a standard candle's intensity at a distance of one centimeter. Specifically, it measures the luminous intensity of a light source emitting light uniformly in all directions. The centimeter candle is defined such that it produces a luminous intensity of one candela when measured at a distance of one centimeter. This unit is particularly significant in fields requiring precise measurements of light and visibility, such as photography, optics, and lighting design. The centimeter candle is not a standard SI unit but serves as a useful metric in specific contexts, particularly in the evaluation of light sources in laboratory settings and specialized applications.
History & Origin
The centimeter candle originated in the 19th century as a response to the need for standardized measurements of light intensity. The development of the electric light bulb and improvements in light measurement technology necessitated a more precise way to quantify illumination. Early light measurement relied on the candle’s physical properties, particularly those of the traditional tallow candle, which varied significantly in brightness. The definition of the centimeter candle aimed to create a consistent measure that could be replicated across different laboratories and practical applications, allowing for more reliable comparisons and assessments of light sources. This was vital as industries began to rely on artificial lighting for a range of applications, from home use to industrial settings.
Etymology: The term 'centimeter' derives from the Latin 'centum' meaning 'hundred' and the Greek 'metron' meaning 'measure'. 'Candle' traces back to the Latin 'candela', which means 'a light or a torch'. Together, they describe a measurement of light intensity at a distance of one centimeter.
