Candela is the basic SI unit of luminous intensity. In other words it is a measure of how bright/intense the human eye perceives the light in a given direction.
I assume you mean candela seconds vs candelas per second. The firstis derived by multiplying candelas by time, the second is achievedby dividing candelas by time
The candela measures luminous intensity, whereas the lumen measures luminous flux. In simple terms, you can think of luminous intensity as being similar to 'brightness', w…hile luminous flux is similar to the rate at which light leaves its source. (MORE)
A candela is the power emitted by a source of light in a set direction with a correction to account for the different sensitivity of the human eye to different wavelengths of …light. One candela is defined as the luminous intensity of a light source emitting light in one direction at a frequency of 540 x 10 12 hertz and has a radiant intensity in that direction of 1/683 watts per steradian.

A candela is a unit of measurement for light sources and light emissions. Light beams projects different color at different wavelengths, and a candela is used to measure the i…ntensity of the light. (MORE)
