The stilb (symbol: sb) is a unit of measurement for illuminance, representing the luminous intensity per unit area. It is primarily used in the field of photometry to quantify how much light is emitted or received by a surface. One stilb is equivalent to one lumen per square meter, making it an essential unit for understanding lighting conditions in various environments.
The stilb is part of the International System of Units (SI) and is standardized to ensure consistency across scientific and engineering applications. This standardization allows for accurate comparisons and calculations in lighting design, photography, and other fields where light measurement is critical.
The concept of measuring light dates back to the early 20th century, with the stilb being introduced as a part of the metric system. Over time, as technology advanced and the need for precise lighting measurements grew, the stilb became an integral part of photometric studies, helping professionals in various industries to optimize lighting conditions.
To convert illuminance from lumens per square meter (lm/m²) to stilbs (sb), you can use the following relationship: 1 sb = 1 lm/m²
For example, if you have a light source that emits 500 lumens over an area of 10 square meters, the illuminance in stilbs would be: 500 lm / 10 m² = 50 sb
Stilbs are commonly used in various applications, including:

The lux-hour (lx·h) is a unit of measurement that quantifies the amount of light received over a period of time. It is derived from the lux, which measures illuminance, and is crucial for assessing lighting conditions in various environments. Understanding lux-hours is essential for architects, interior designers, and anyone concerned with optimal lighting.
The lux-hour is standardized under the International System of Units (SI). One lux is defined as one lumen per square meter, and when you multiply this by time in hours, you obtain lux-hours. This standardization ensures that measurements are consistent and universally understood, making it easier to compare lighting conditions across different settings.
The concept of measuring light dates back to the early 20th century when scientists began to understand the importance of light in various applications. The lux was officially defined in 1948, and since then, the lux-hour has evolved as a practical tool for measuring light exposure over time. This evolution has led to its widespread use in fields such as photography, agriculture, and health sciences.
To illustrate how to calculate lux-hours, consider a scenario where a workspace is illuminated with a light source providing 500 lux for 3 hours. The calculation would be as follows:
[ \text{Lux-Hours} = \text{Illuminance (lux)} \times \text{Time (hours)} ] [ \text{Lux-Hours} = 500 , \text{lx} \times 3 , \text{h} = 1500 , \text{lx·h} ]
This means that the workspace received a total of 1500 lux-hours of light during that period.
Lux-hours are particularly useful in various applications, including:
