How many square Metres is a lux?

One lux is equal to one lumen per square metre: 1 lx = 1 lm/m2 = 1 cd. sr/m2. A flux of 1000 lumens, spread uniformly over an area of 1 square metre, lights up that square metre with an illuminance of 1000 lux.

How many lumens do I need per square metre?

The basic formula is to multiply the square meterage of the room by the lux requirement. As an example, a 10 square meter living room that needs 100-200 lux would need 1,000-2,000 lumens. However, a 10 square meter kitchen at 300-400 lux would need 3,000-4,000 lumens.

How do you calculate lux level?

What is lux on a light meter?

One unit of measurement is called a lux, which describes how much light falls on a certain area. (This is different from a unit of lumens, which tells you the total amount of light emitted by a light source.) The number of lux gets smaller as you get farther away from a light source.

How many lux is full sun?

that “direct sunlight” is between 32,000 and 100,000 lux.

How do you calculate lux room size?

To calculate this result:

  1. Compute the area of the room: area = 4 m × 5 m = 20 m²
  2. Choose the right amount of lux you need. For a studio, the recommended value is 323 lx .
  3. Find the result using the formula: lux = lumens × area = 323 lx × 20 m² = 6,460 lm.
