Lighting intensity lux
WebLux is a measurement used by lighting designers to quantify the effect of an interior lighting scheme. Luminous flux is a measurement of the total amount of light a light source emits, integrated over the entire angular span of the light. We quantify luminous flux in units of lumens (lm), a photometric unit of measurement. WebThe illuminance Ev in lux (lx) is equal to 10.76391 times the power P in watts (W), times the luminous efficacy η in lumens per watt (lm/W) divided by the surface area A in square feet (ft 2 ): Ev (lx) = 10.76391 × P(W) × η(lm/W) / A(ft 2) Watts to …
