The lumen (symbol: lm) is the SI unit of luminous flux, a measure of the total quantity of visible light emitted by a source per unit of time. It quantifies the perceived power of light as it relates to human vision, making it an essential measurement in fields such as photography, lighting design, and architecture.
The lumen is standardized under the International System of Units (SI) and is defined based on the luminous efficacy of radiant energy. One lumen is equivalent to the light emitted by a uniform source of one candela over a solid angle of one steradian. This standardization ensures consistency in lighting measurements across various applications.
The concept of the lumen has evolved over time, with its origins tracing back to the early studies of light and vision. The term "lumen" was first introduced in the late 19th century as scientists sought to quantify light output in a way that was relatable to human perception. Over the decades, advancements in technology and a deeper understanding of photometry have led to the refinement of the lumen as a standard unit of measurement.
To illustrate the use of the lumen, consider a light bulb that emits 800 lumens. If you want to determine how many lumens are required for a room of 100 square feet to achieve a recommended illuminance level of 50 lux, you would calculate it as follows:

The candela (symbol: cd) is the SI unit of luminous intensity, representing the amount of light emitted by a source in a particular direction. It is a fundamental unit in photometry, which is the science of measuring visible light as perceived by the human eye. The candela is crucial for understanding how light interacts with our environment, making it essential for various applications in lighting design, photography, and visual arts.
The candela is standardized based on the light emitted by a source that radiates monochromatic light at a frequency of 540 terahertz (THz) and has a radiant intensity of 1/683 watt per steradian. This standardization ensures consistency in measurements across different contexts and applications, allowing professionals to rely on accurate and comparable data.
The concept of the candela has evolved significantly since its inception. Initially, it was based on the light produced by a specific type of candle. However, as science progressed, the need for a more precise and universally applicable unit became evident. The candela was officially adopted as part of the International System of Units (SI) in 1979, reflecting advancements in photometric measurements and technology.
To illustrate the use of the candela, consider a light source that emits a luminous intensity of 100 candelas. If you want to calculate the total luminous flux (in lumens) emitted by this source over a solid angle of 1 steradian, you would use the formula: [ \text{Luminous Flux (lm)} = \text{Intensity (cd)} \times \text{Solid Angle (sr)} ] Thus, for our example: [ \text{Luminous Flux} = 100 , \text{cd} \times 1 , \text{sr} = 100 , \text{lm} ]
The candela is widely used in various fields, including:
