Lumens to Candela
 Enter Luminous Flex in Lumens : lm Enter Apex Angle in Degrees : ° Luminous Intensity Result in Candela : cd
##### 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.
