Potencia eléctrica en vatios (W) to illumenance in lux (lx) calculator and how to calculate.
Ingrese la potencia en watts, luminous efficacy in lumens per watt, surface area in square feet / meters or spherical radius in feet / meters and press the Calcular button to get the illumenance in lux:
* the predefened luminous efficacy values are typical / average values.
The illumenance Ev en lux (lx) is equal to 10.76391 times the potencia P in vatios (W), times the luminous efficacy η en lumens per watt (lm/W) divided by the surface area A en square feet (ft2):
Ev(lx) = 10.76391 × P(W) × η(lm/W) / A(ft2)
The illumenance Ev en lux (lx) is equal to the potencia P in vatios (W), times the luminous efficacy η en lumens per watt (lm/W) divided by the surface area A en square meters (m2):
Ev(lx) = P(W) × η(lm/W) / A(m2)
