Brightness, represented by the symbol br, is a measure of the amount of light that is emitted or reflected from a surface. It is often quantified in terms of illuminance, which refers to the amount of luminous flux per unit area. This measurement is crucial in various fields, including photography, architecture, and lighting design, as it helps determine how well-lit a space is.
Brightness is standardized using units such as lux (lx) and foot-candle (fc). One lux is defined as one lumen per square meter, while one foot-candle is equivalent to one lumen per square foot. Understanding these units is essential for accurately measuring and converting brightness levels in different environments.
The concept of brightness has evolved significantly over time. Early measurements were based on subjective assessments of light intensity. However, with advancements in technology and the development of photometric standards, brightness is now measured using precise instruments. The introduction of digital light meters has further enhanced our ability to quantify brightness accurately.
To illustrate how to convert brightness levels, consider a scenario where you have a light source emitting 1000 lumens over an area of 10 square meters. The illuminance can be calculated as follows:
[ \text{Illuminance (lux)} = \frac{\text{Luminous Flux (lumens)}}{\text{Area (m²)}} ]
[ \text{Illuminance} = \frac{1000 \text{ lumens}}{10 \text{ m²}} = 100 \text{ lux} ]
Brightness measurements are vital in various applications, including:

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:
