Unit Explanations
Lumen per Square Meterlm/mĀ²
Source UnitThe lumen per square meter (lm/mĀ²), also known as the lux, quantifies the illuminance received on a surface. It is defined as one lumen of luminous flux spread uniformly over an area of one square meter. This unit is integral to the field of photometry, which studies visible light in terms of its perception by the human eye. The lux helps in assessing how well a space is illuminated, which is vital for ensuring comfort and safety in various environments. As such, it plays a critical role in architectural design, photography, and horticulture. The lumen per square meter is thus essential for evaluating how light affects various surfaces, materials, and living organisms.
Current Use
The lumen per square meter is widely used across multiple industries today, especially in architecture and interior design, where it is crucial to ensure that spaces have adequate lighting for both aesthetic and functional purposes. In the horticultural sector, lux measurements are essential for determining the light needs of plants, influencing growth and yield. The entertainment industry, particularly in photography and cinematography, also relies on lux for lighting setups to achieve desired visual effects. Moreover, in health and safety regulations, lux levels are often specified to ensure that workplaces meet minimum illumination standards for safety. Countries across Europe and North America use lux as a standard measurement for lighting levels in various applications, from residential to commercial and industrial settings.
Fun Fact
The lux is named after the Latin word for light, 'luxus'.
Luxlx
Target 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).

The lumen per square meter is thus essential for evaluating how light affects various surfaces, materials, and living organisms.
History & Origin
The concept of measuring light intensity dates back to ancient civilizations, where natural light was used to determine time and space. The development of the lumen as a unit came with the rise of scientific studies on light in the 19th century, especially with the work of scientists like Pierre Bouguer and Johann Heinrich Lambert. These studies laid the groundwork for later precise measurements of light.
Etymology: The term 'lumen' is derived from the Latin word for 'light.' The square meter (mĀ²) is a standard unit of area in the metric system, representing a square with sides of one meter.

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.
