5500 lux over an area of 1 square meter equals 5500 lumens.
Lux measures illuminance, which is lumens per square meter. So, to convert lux to lumens, you multiply the lux value by the area in square meters. Assuming the area is 1 m², 5500 lux directly converts to 5500 lumens.

Conversion Formula
The formula to convert lux to lumens is:
Lumens = Lux × Area (in square meters)
This works because lux is a measurement of luminous flux per unit area, so multiplying by the area gives the total luminous flux, in lumens.
For example, if you have 5500 lux shining on an area of 1 square meter, the calculation is:
- Lux = 5500
- Area = 1 m²
- Lumens = 5500 × 1 = 5500 lumens
If the area were 2 square meters instead, then lumens would be 5500 × 2 = 11000 lumens.
Conversion Example
- Example 1: 3000 lux on 1 m²
- Multiply 3000 by 1
- Lumens = 3000 × 1 = 3000 lumens
- Example 2: 4500 lux on 0.5 m²
- Multiply 4500 by 0.5
- Lumens = 4500 × 0.5 = 2250 lumens
- Example 3: 6000 lux on 1.2 m²
- Multiply 6000 by 1.2
- Lumens = 6000 × 1.2 = 7200 lumens
- Example 4: 10000 lux on 0.75 m²
- Multiply 10000 by 0.75
- Lumens = 10000 × 0.75 = 7500 lumens

Conversion Definitions
Lux: Lux measures the intensity of light hitting a surface, calculated as lumens per square meter. It shows how much light is spread over an area, helping to understand brightness from the human eye perspective in a defined space. It depend on both light source strength and distance.
Lumens: Lumens quantify the total amount of visible light emitted by a source in all directions. Unlike lux, lumens do not consider area, only the total light output. It’s used to rate how bright a bulb or fixture is without regard to where the light falls.
Conversion FAQs
Why does converting lux to lumens require area measurement?
Lux is a measure of illuminance, which is lumens per square meter. Without knowing the area the light covers, you cannot find the total luminous flux (lumens). The same lux value over a larger area means more total lumens, so area must be included in conversion.
Can I convert lux to lumens if the light is unevenly distributed?
If light distribution isn’t even, a single lux value may not represent the whole area accurately. To convert to lumens properly, you’d need the average lux over the area or detailed measurements for different sections, then sum the lumens for each part.
Does the color of light affect lux to lumen conversion?
No, the conversion itself doesn’t depend on light color. However, human eye sensitivity varies with wavelength, so lux measurements can be influenced by light color while lumens represent total visible light output weighted for human vision.
How accurate is the assumption of 1 square meter for lux to lumens?
Assuming 1 m² is a simplification. In reality, the area illuminated can be larger or smaller. Without exact area, the lumens value calculated from lux will not be precise, just an estimate based on that assumption.
Is it possible to get lumens from lux in outdoor lighting conditions?
Yes, but outdoor lighting usually covers irregular areas and changing distances, making direct conversion complex. Accurate lumens calculation requires measuring the actual illuminated area or using specialized instruments.
