5500 lux corresponds to 5500 lumens when measured over an area of 1 square meter.
Lux measures illuminance, which is lumens per square meter. So, converting 5500 lux to lumens depends on the surface area illuminated. Assuming the area is 1 m², 5500 lux equals 5500 lumens since 1 lux = 1 lumen/m².

Conversion Formula
Lux is the measure of illuminance, the amount of light falling on a surface per unit area, measured in lumens per square meter (lm/m²). Lumens measure the total quantity of visible light emitted by a source.
The formula to convert lux to lumens is:
Lumens = Lux × Area (in square meters)
This works because lux is lumens divided by area. To find total lumens, multiply illuminance by the area illuminated. Without knowing the area, converting lux to lumens isn’t exact.
Example calculation:
- Given: 5500 lux, Area = 1 m²
- Calculate: Lumens = 5500 × 1 = 5500 lumens
- If area = 2 m², Lumens = 5500 × 2 = 11000 lumens
Conversion Example
- Convert 3000 lux to lumens over 1.5 m²:
- Multiply 3000 × 1.5
- Result: 4500 lumens
- Convert 7200 lux over 0.75 m²:
- Calculate 7200 × 0.75
- Result: 5400 lumens
- Convert 4200 lux over 3 m²:
- Multiply 4200 × 3
- Result: 12600 lumens
- Convert 1500 lux over 0.5 m²:
- Multiply 1500 × 0.5
- Result: 750 lumens
- Convert 9800 lux over 2 m²:
- Calculate 9800 × 2
- Result: 19600 lumens

Conversion Definitions
Lux: Lux is a unit measuring illuminance, representing the amount of light falling on a surface per square meter. It quantifies perceived brightness as lumens per square meter, used in lighting design and photography to measure light intensity at a point.
Lumens: Lumens measure the total visible light emitted by a source in all directions. It reflects the brightness as perceived by the human eye, indicating how much light a bulb or fixture produces without regard to direction or surface area.
Conversion FAQs
Why can’t I convert lux to lumens without knowing the area?
Lux measures light intensity per unit area, while lumens measure total light output. Without the surface area illuminated, the total lumens cannot be determined from lux alone, because the same lux value over differing areas produces different lumens.
What happens to lumens if the lux value is constant but the area increases?
When lux remains the same, increasing the surface area results in higher lumens, since lumens equals lux multiplied by area. So doubling the area doubles the total lumens. It shows total light output changes with illuminated space size.
Is it correct to assume 1 lux equals 1 lumen?
No, 1 lux equals 1 lumen per square meter. The two units measure different things; lux depends on area while lumens measure total light output. Only when the area is exactly 1 m² does 1 lux equal 1 lumen numerically.
How precise is converting lux to lumens in practical situations?
Conversion precision depends on knowing the exact surface area and uniformity of light distribution. If area or light spread varies, calculated lumens may not reflect actual light output accurately, making assumptions necessary when exact data lacks.
Can lux to lumens conversion be used for irregular surfaces?
It’s challenging since lux measures light intensity on flat surfaces, and irregular shapes affect light distribution unevenly. Calculating lumens requires integrating varying lux values over the surface, complicating direct conversions for irregular geometries.
