Elara Bennett1300 lux converts to 1300 lumens when the illuminated area is exactly 1 square meter.
Lux measures illuminance or brightness on a surface, while lumen is the total amount of visible light emitted by a source. Since 1 lux equals 1 lumen per square meter, converting lux to lumen requires multiplying by the area in square meters.

Conversion Formula
The formula to convert lux to lumen is:
Lumens = Lux × Area (in square meters)
Lux measures how much light falls on a surface area, lumen measures total light output. So, if you know how bright the surface (lux) and how big the surface area is, you multiply them to find total light emitted over that area.
Example: If you have 1300 lux shining on 1 square meter, then lumens = 1300 × 1 = 1300 lumens.
If the area were 2 square meters, lumens = 1300 × 2 = 2600 lumens.
Conversion Example
- Convert 1000 lux on 0.5 m² area to lumen:
- Multiply 1000 lux by 0.5 m² → 1000 × 0.5 = 500 lumens.
- This means 500 lumens total light is hitting that 0.5 m² surface.
- Convert 800 lux on 2 m² area:
- 800 lux × 2 m² = 1600 lumens.
- The larger the area, the more total lumens for same lux.
- Convert 1500 lux on 0.75 m²:
- 1500 × 0.75 = 1125 lumens.
- Shows how area affects total lumen count.
- Convert 2000 lux on 1.2 m²:
- 2000 × 1.2 = 2400 lumens.
- More area means more lumens for same illuminance.
- Convert 500 lux on 3 m²:
- 500 × 3 = 1500 lumens.
- Lower lux but higher area can equal more lumens.

Conversion Definitions
Lux: Lux measures illumination on a surface area; it tells how much visible light falls on each square meter. One lux equals one lumen per square meter, so lux quantifies brightness perceived by an area rather than total light emitted.
Lumen: Lumen is a unit measuring total quantity of visible light emitted by a source, regardless of direction. It represents brightness output, independent of area illuminated, unlike lux that depends on surface size.
Conversion FAQs
Can I convert lux to lumen without knowing the surface area?
No, you cant convert lux to lumen accurately without knowing the area. Lux measures illumination per unit area, lumen measures total light output. Without the size of illuminated surface, conversion is incomplete.
Does higher lux always mean more lumens?
Not necessarily. Higher lux means more light per square meter, but total lumens depend on area size too. A small area with high lux might have fewer lumens than a large area with lower lux.
Is the conversion formula different indoors and outdoors?
The formula Lumens = Lux × Area stays same regardless of environment. What changes is how light spreads or reflects, but calculation method remains consistent.
Why is lux preferred over lumen for room lighting design?
Lux reflects brightness on surfaces, which is what matters for human eyes in rooms. Lumens tells total light emitted but not how its distributed, so lux better guides lighting placement.
Can I use lux and lumen interchangeably?
No, lux and lumen measure different things. Lux is light intensity on surfaces, lumen is total light output. They relate through area but are not the same unit.
