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.
Watts :
  • The watt is a unit of power or radiant flux.In the International System of Units and then it is defined as a derived unit of 1 kg·m²·s³ or, equivalently, 1 joule per second.
  • It is used to quantify the rate of energy transfer.
  • Then, the symbol fo watts is W.
Lumens to Watts :
  • Lumen is the term used to describe the total amount of light emitted by a light source, while wattage merely indicates the amount of energy it uses.
  • As lighting becomes more and more energy-efficient, the same number of lumens is being achieved with lower and lower wattages.
Formula :
  • The formula used to calculate the following calculator lumens to watts is given below.
  • Whether, Select the light source or Enter luminous efficacy in lumens per watt.
  • Then, the calculation formula = Luminous flux in Lumens / Luminous efficacy in lumens per watt.
  • Besides the formula this calculator works.
How to Calculate ?
  • First, Enter the Luminous flux in lumens.
  • Second, Select the light source or Enter Luminous efficacy in lumens per watt.
  • 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 Power result in watts.
