Candela Candela The candela ( or ; symbol: cd) is the base unit of luminous intensity in the International System of Units (SI); that is, luminous power per unit solid angle emitted by a point light source in a particular direction. Luminous intensity is analogous to radiant intensity, but instead of simply adding up the contributions of every wavelength of light in the source's spectrum, the contribution of each wavelength is weighted by the standard luminosity function (a model of the sensitivity of the human eye to different wavelengths). A common wax candle emits light with a luminous intensity of roughly
Rosario Candela Italian-American architect, Gaetan Ajello. After another brief stint with the firm of Frederick Sterner, Candela set up his own practice in 1920. His first major commission was for an apartment house at West 92nd Street and Broadway. Shortly thereafter, he received his first commission for an East Side apartment at 1105 Park Avenue.
