📌 Standard Benchmark Reference Values
Perfectly diffusing Lambertian surface emitting 1 lm/cm² (10,000/π cd/m²).
Exact RatioAbout Lambert (L)
A CGS unit of luminance representing the luminance of a perfectly diffusing surface emitting 1 lumen per square centimeter (1 L = 10,000/π cd/m² ≈ 3,183.1 cd/m²).
History: Named in honor of Swiss mathematician and physicist Johann Heinrich Lambert (1728–1777), author of "Photometria".
Common Uses: Historical optics treatises, optical diffusion calculations, high-brightness surface photometry.
About Candela per Square Meter (cd/m²)
The SI coherent derived unit of luminance, representing the luminous intensity per unit projected area of an emitting or reflecting surface.
History: Standardized by the CIE and BIPM as the definitive metric quantity for perceived surface brightness.
Common Uses: Electronic display screen brightness ratings, roadway lighting design, architectural glare calculations.
