What are Lumen and Candela

Lumen is a unit of measurement for luminous flux, which quantifies the total amount of visible light emitted by a source. Unlike other light measurements that focus on intensity or brightness, lumen evaluates the perceived power of light to the human eye. It accounts for the spectral sensitivity of vision, placing more emphasis on green and yellow wavelengths, which are more easily detected by the eye. A higher lumen value indicates a brighter light source. Understanding lumens is essential for designing efficient lighting systems and for comparing the performance of different light sources in various environments.

Candela is a fundamental unit of luminous intensity in the International System of Units (SI). It measures the power emitted by a light source in a particular direction, weighted by the luminosity function, which represents the sensitivity of the human eye to different wavelengths. One candela equates to the luminous intensity of a source that emits monochromatic light at a frequency of 540 terahertz with a radiant intensity of 1/683 watt per steradian. The concept of candela is pivotal in fields like lighting design and photometry, as it provides a standard for quantifying how light is perceived in terms of brightness.
