Lumens :
  • The lumen is the unit of luminous flux, a measure of the total quantity of visible light emitted by a source per unit of time, in the International System of Units.
  • Then, the symbol of lumens is lm.
Candela :
  • The candela is the unit of luminous intensity in the International System of Units.
  • It measures luminous power per unit solid angle emitted by a light source in a particular direction.
  • Then, the symbol of candela is cd.
Lumens to Candela :
  • Lumens refers to the total amount of light a lighting apparatus emits.
  • We represent lumens as L.
  • The higher the lumens value of a lighting device, the greater the area it illuminates.
  • On the other hand, candela refers to the amount of light emitted by a lighting device in a particular direction.
Formula :
  • The formula used to calculate the following calculator Lumens to Candela is given below.
  • The apex angle in degrees value should be in assingment operator.
  • So, the apex angle in degrees = Math.PI/180.
  • Then the calculation formula = Enter Luminous flex in lumens / ( 2 * Math.PI * ( 1 – Math.cos ( The apex angle in degrees / 2 ))).
  • Besides the formula this calculator works.
How to Calculate ?
  • First, Enter the Luminous flex in lumens.
  • Second, Enter the Apex angle in degrees.
  • Click “Calculate” to get the result and then if you want to clear values Click “Reset” in addition to clear the values.
  • Finally, follow these steps to get the results.
  • Then you will get as a Luminous intensity result in candela.
