Candle Power Definition PhysicsCandela (cd), unit of luminous intensity in the International System of Units (SI), defined as the luminous intensity in a given direction of a source that emits monochromatic radiation of frequency 540 × 1012 hertz and has a radiant intensity. One candlepower was the light produced by a pure spermaceti candle weighing one sixth of a pound and burning at a rate of 120 grains per hour Germany Austria and Scandinavia used the Hefnerkerze a unit based on the output of a Hefner lamp

Some of the specific objects and relationships astronomers have used as “standard candles” include: spectrally classified stars on the stellar main sequences, certain types of variable stars, the relationship between a galaxy’s rotation speed and its luminosity, and type Ia supernovae.
