1300 lux corresponds to 13000 lumens when converted assuming an area of 10 square meters. Lux measures luminous flux per square meter, so lumen equals lux multiplied by the area in square meters.
To convert lux to lumen, the surface area where the light falls must be known. Lux is lumens per square meter, so multiplying lux by the area gives total lumens. Without area, lux alone can’t determine lumen.

Conversion Formula
The conversion from lux to lumen requires multiplying the lux value by the surface area in square meters where the light is spread. The formula is:
Lumen (lm) = Lux (lx) × Area (m²)
Lux measures luminous flux per unit area, so to get total luminous flux (lumens), you need to multiply lux by area. Without the area, lux can’t be converted directly.
For example, if you have 1300 lux on a surface of 10 m², the calculation is:
- 1300 lx × 10 m² = 13000 lumens
Conversion Example
Below are different lux values converted to lumen assuming the same 10 m² area:
- 1200 lux:
- Multiply 1200 lx by 10 m²
- 1200 × 10 = 12000 lumens
- 1350 lux:
- 1350 × 10 = 13500 lumens
- 1280 lux:
- 1280 × 10 = 12800 lumens
- 1310 lux:
- 1310 × 10 = 13100 lumens
- 1295 lux:
- 1295 × 10 = 12950 lumens

Conversion Definitions
Lux: Lux is a unit measuring luminous flux per square meter, representing the intensity of light that hits or passes through a surface. It quantifies brightness perceived by the human eye, factoring in both the light source and distance from it.
Lumen: Lumen is a unit measuring total visible light emitted from a source. It indicates the quantity of light perceived by the human eye, regardless of direction or area, showing the overall brightness produced by a lamp or bulb.
Conversion FAQs
Why does the surface area matter when converting lux to lumen?
Lux measures illumination per unit area, so to find total light output (lumens), the area receiving light must be known. Without area, lux value only shows intensity on a surface, not total luminous flux.
Can I convert lux to lumen without knowing the area?
No, because lux is lumens divided by area, the area is required to reverse the calculation. Without it, you can’t accurately find total lumens from lux alone.
Is the conversion factor always 10 when converting lux to lumens?
No, the factor depends completely on the surface area where light is measured. The example uses 10 square meters, but any other area changes the factor.
How does distance affect lux and lumen values?
Lux decreases as distance from the light source increases because the same amount of light spreads over larger area. Lumen stays constant as it measures total light emitted, not intensity on surface.
Are lux and lumen interchangeable units?
No, lux and lumen measure different things. Lux is intensity per area, lumen is total light output. They relate by area, but they cannot be used interchangeably without additional info.
