About Luminous Intensity
Luminous intensity is how much light a source throws in one direction, measured in candelas. The candela is one of the seven SI base units, and it's roughly the output of a single household candle — which is where the name came from. Candlepower, the Hefner candle and the carcel unit are older national standards from before it was defined.
