5500 lux corresponds to 5500 lumens when the illuminated surface area is 1 square meter. This is because lux measures luminous flux per area, so converting lux to lumens requires multiplying by the area in square meters.
In detail, lux quantifies light intensity hitting a surface, while lumens express total light output. If the surface area is known, multiplying lux by that area gives lumens. For 1 m², 5500 lux equals 5500 lumens.

Conversion Formula
The basic formula to convert lux (lx) to lumens (lm) is:
Lumens = Lux × Area (in square meters)
Lux measures how many lumens fall on a square meter. So, to find the total lumens, multiply the lux value by the surface area illuminated.
For example, if a surface has 5500 lux and the area is 1 m²:
- Lux = 5500 lx
- Area = 1 m²
- Lumens = 5500 lx × 1 m² = 5500 lm
If the area was 2 m², the lumens would double to 11000 lm.
Conversion Example
- Given 3000 lux on a 2 m² surface:
- Multiply 3000 lx by 2 m²
- 3000 × 2 = 6000 lumens
- Result: 6000 lm total light output
- For 10000 lux on 0.5 m²:
- 10000 × 0.5 = 5000 lumens
- Half the area halves the total lumens
- At 7500 lux over 3 m²:
- 7500 × 3 = 22500 lumens
- Total light output increases with area
- For 4250 lux at 1.2 m²:
- 4250 × 1.2 = 5100 lumens
- Multiply lux by area to get lumens

Conversion Definitions
Lux: Lux is a unit measuring the intensity of light that hits or illuminates a surface area, defined as one lumen per square meter. It quantifies how bright the surface appears based on the luminous flux spread over that area, making it useful for lighting design and measurement.
Lumens: Lumens measure the total amount of visible light emitted by a source in all directions. It represents the luminous flux perceived by the human eye, which helps to compare brightness between different light sources regardless of direction or distance from any surface.
Conversion FAQs
Can I convert lux to lumens without knowing the surface area?
No, lux measures luminous flux per unit area, so without knowing the exact surface area illuminated, converting lux to total lumens is impossible. Lumens depend on how large the area is that receives the light.
Why does 5500 lux equal 5500 lumens only at 1 square meter?
Because lux is lumens divided by area, at exactly 1 m², the number of lumens equals the lux value. If the area increases or decreases, the total lumens change proportionally, so this equivalence holds only for 1 m².
What happens if the surface is irregular or uneven?
Lux assumes uniform light distribution. On irregular surfaces, the lux reading varies across points, so total lumens calculation becomes complex and requires integrating lux over the entire surface area.
Is the conversion affected by light source type?
The conversion from lux to lumens depends only on area and light intensity, not on light source type. However, different sources may emit light with different spatial distributions, affecting local lux measurements.
How precise is the conversion for practical lighting setups?
The conversion is exact mathematically, but real-world factors like reflectance, shadows, and measurement errors cause variations. Surface texture and angle also influence lux readings, so lumens calculated are approximate in practice.
