It has become common and ingrained in our minds to think of how bright a light bulb or light fixture is based on its wattage. A 60-watt bulb meant you got 60 watts of light. That’s how it’s been for decades. But watts are not a measure of light output. Rather, they are a measure of how much energy a light source is consuming.

The problem is that lux and W/cm2 are not simply different units, rather they are units for different measurements. mW/cm2 is a unit for irradiance (energy falling on 

Enter Surface Area: Lux and intensity Lux is a unit of light measurement where the area is also taken into account. 1 lux equals 1 Lumen/m2, in other words – light intensity in a specific area. Lux is used to measure the amount of light output in a given area. One lux is equal to one lumen per square meter. The lux (symbol: lx) is the SI derived unit of illuminance, measuring luminous flux per unit area. It is equal to one lumen per square metre.

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): P (W) = 0.09290304 × E v(lx) × A (ft 2) / η (lm/W) Lux to watts calculation with area in square meters watts = 0.09290304 × lux × (square feet) / (lumens per watt) or. W = 0.09290304 × lx × ft 2 / (lm/W) Example. What is the power consumption with illuminance of 50 lux, luminous efficacy of 15 lumens per watt and surface area of 200 square feet?

2014-01-11 · Lux are units of lumen/square meter, which relates in a way to watts (of light) per square meter. Good office lighting is about 500 lux. A camera uses a lux measurement to determine lighting at the subject for a good quality picture. The lumen relates to the relative brightness we can see, which is called the photopic response (human eye).
