Candela measures the brightness of a light source in a specific direction, while lux measures the amount of light that falls on a surface per unit area. Candela is a measure of luminous intensity, while lux is a measure of illuminance.
Lux and candela are both units of measurement for light intensity, but they measure different aspects of light. Lux measures the amount of light that falls on a surface, while candela measures the brightness of a light source in a specific direction. Lux is used to determine the brightness of an illuminated area, while candela is used to measure the intensity of a light source. In essence, lux measures the light that is received, while candela measures the light that is emitted.
Lumens measure the total amount of light emitted by a source, candela measures the intensity of light in a specific direction, and lux measures the amount of light that falls on a surface. Lumens indicate overall brightness, candela measures brightness in a specific direction, and lux measures brightness on a surface.
Light intensity is also known as luminosity. Candela is the si unit
Foot Candela is the measuring unit for illuminance while candela/meter squared is a measuring unit for luminance,which makes conversion not possible. conversion can be done for units of the same quantity, for example, illuminance units : ft candela = 10.764 lux. To know the difference between luminance & illuminance, you can take a look at http://www.tpub.com/content/gsacriteria/gsa_courtroom_lighting/gsa_courtroom_lighting0012.htm
Candela measures the intensity of light emitted in a specific direction, lumens measure the total amount of light emitted by a source, and lux measures the amount of light that falls on a surface. Candela is used for directional light sources like flashlights, lumens for overall brightness of a light source, and lux for the brightness of light on a surface.

Intensity is measured in Candela. Candela is its SI unit.
candela--------------------------------------------The official international definition of candela (1979) is:"The candela is the luminous intensity, in a given direction, of a source that emits monochromatic radiation of frequency 540 x 10e12 hertz and that has a radiant intensity in that direction of 1/683 watt per steradian".
Lumens measure the total amount of light emitted by a source, candela measures the intensity of light in a specific direction, and lux measures the amount of light that falls on a surface. Lumens indicate overall brightness, candela measures brightness in a specific direction, and lux measures brightness on a surface.

candela
The meter is a unit of length, the candela is a unit of luminous intensity.
The SI unit of Intensity of light is CANDELA.
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 intensity of the light.

The symbol of candela is cd. The luminous intensity or candlepower of a light is expressed in candelas.
