5000 lux converted to lumen depends on the area illuminated; assuming 1 square meter, 5000 lux equals 5000 lumens.
Lux measures illuminance (lumens per square meter), so to convert lux to lumen you multiply lux value by the area in square meters. Without knowing area, lux alone can’t convert to lumens directly.

Conversion Formula
The conversion from lux to lumen is done by multiplying the lux value by the area in square meters being illuminated. Lux (lx) represents lumens per square meter (lm/m²), so:
Lumens (lm) = Lux (lx) × Area (m²)
This works because lux measures how much luminous flux hits a surface area. So, if you know the lux on a surface and the surface size, multiplying them gives total lumens emitted.
Example: For 5000 lux on 2 m² surface area:
- Lux = 5000 lx
- Area = 2 m²
- Lumens = 5000 × 2 = 10000 lm
Conversion Example
- Example 1: 3000 lux on 1.5 m²
- Calculate lumens by multiplying: 3000 × 1.5
- Result: 4500 lumens
- Example 2: 7500 lux on 0.8 m²
- Multiply lux by area: 7500 × 0.8
- Lumens: 6000 lm
- Example 3: 1200 lux on 3 m²
- Lumens = 1200 × 3
- Result: 3600 lm
- Example 4: 4500 lux on 2.2 m²
- Calculate: 4500 × 2.2
- Lumens: 9900 lm

Conversion Definitions
Lux: Lux is a unit measuring illuminance, the amount of luminous flux landing on a surface per square meter. It tells how bright the surface appears and depends on both the light source’s intensity and the distance from it.
Lumen: Lumen quantifies the total amount of visible light emitted by a source. It measures luminous flux, indicating how much light is produced regardless of where it spreads or hits.
Conversion FAQs
Why can’t I convert lux to lumen without knowing the area?
Lux measures light per unit area, so without area info, the total light output (lumens) can’t be found. Lumens depend on total light emitted, while lux is about intensity on a certain surface size. Area is needed to scale lux back to lumens.
Does a higher lux value mean higher lumens always?
Not always. Lumens depends on both lux and area. A very bright light on a tiny area may have high lux but low total lumens. Conversely, lower lux on a large area can have more lumens. Both values relate but describe different things.
How precise is converting lux to lumens using a fixed area?
Using a fixed area (like 1 m²) gives an approximate lumens value. Real surfaces vary in size and shape, so exact lumens requires exact measurement of illuminated area. Assumptions lead to rough estimates, not exact figures.
Can lux values change if the distance between light and surface changes?
Yes, lux decreases as distance increases because light spreads over larger area. Lumens stay same since total light output doesn’t change, but lux depends on how concentrated light is on a surface.
Is it possible for two different lux values to have same lumens?
Yes, if the areas differ. Higher lux on smaller area and lower lux on bigger area can produce same lumens. Lumens is total output, lux is intensity per square meter, so area changes relationship between them.
