Lux to Watts :

Lux to Watts
Lux :
  • Light or visible light is electromagnetic radiation that can be perceived by the human eye.
  • Visible light is usually defined as having wavelengths in the range of 400–700 nanometres, corresponding to frequencies of 750–420 terahertz, between the infrared and the ultraviolet.
  • Then, the symbol of lux is lx.
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.
Lux to Watts :
  • Watt and lux units represent different physical quantities, so you can’t convert them directly.
  • Our application calculates and converts watts to lux to show how power affects the light efficiency on a given surface.
  • A higher number of lux makes the source more efficient in spreading (the surface is brighter), and a lower one means that your surface is darker, dimmer.
Formula :
  • The formula used to calculate the following calculator lux to watts is given below.
  • The calculation formula,
    • So, Feet = ( Illuminance in lux * Surface area / Luminous efficacy in lumens per watt ) * 0.09290304.
    • Then, Meter = ( Illuminance in lux * Surface area / Luminous efficacy in lumens per watt ).
  • Besides the formula this calculator works.
How to Calculate ?
  • First, Enter Illuminance in lux.
  • Second, Either select light source or enter Luminous efficacy in lumens per watt.
  • Third, Select  Feet or Meter.
  • Fourth, Either enter spherical radius or enter surface area.
  • 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.
