Watts = 0.09290304 × lux × (square feet) / (lumens per watt) So the power P in watts (W) is equal to the 0.09290304 times the illuminance E v in lux (lx) times the surface area A in square feet (ft 2), divided by the luminous efficacy η in lumens per watt (lm/W): The power P in watts (W) is equal to the luminous flux Φ V in lumens (lm), divided by the luminous efficacy η in lumens per watt (lm/W): ![]() The luminous flux Φ V in lumens (lm) is equal to 0.09290304 times the illuminance E v in lux (lx) times the surface area A in square feet (ft 2): Lux to watts calculation formula Lux to watts calculation with area in square feet Lux to watts calculation with area in square meters.Lux to watts calculation with area in square feet.Lux and watt units represent different quantities, so you can't convert lux to watts. You can calculate watts from lux, luminous efficacy and surface area. How to convert illuminance in lux (lx) to electric power in watts (W). * the predefined luminous efficacy values are typical / average values.
