2400 lux corresponds to 2400 lumens when measured over an area of 1 square meter. This is because lux measures illuminance (lumens per square meter), so 2400 lux on 1 m² equals 2400 lumens.
Lux is the measure of light intensity hitting a surface, while lumens measure the total amount of light emitted. To convert lux to lumens, you multiply the lux value by the area in square meters illuminated. For 2400 lux over 1 m², the total lumens is 2400.

Conversion Formula
The formula to convert lux to lumens depends on the surface area illuminated. Lux is lumens per square meter, so:
Lumens = Lux × Area (in square meters)
For example, if you have 2400 lux and the area is 1 m², the calculation is:
- Multiply 2400 (lux) by 1 (m²)
- 2400 × 1 = 2400 lumens
If the area was 2 m², the lumens would be 2400 × 2 = 4800 lumens. The formula works because lux measures how many lumens fall on a given area.
Conversion Example
- Example 1: Convert 1500 lux over 1 m²
- Multiply 1500 lux by 1 m²
- 1500 × 1 = 1500 lumens
- The total light emitted is 1500 lumens
- Example 2: Convert 3000 lux over 0.5 m²
- Multiply 3000 lux by 0.5 m²
- 3000 × 0.5 = 1500 lumens
- Though lux is higher, smaller area means total lumens is 1500
- Example 3: Convert 500 lux over 4 m²
- Multiply 500 lux by 4 m²
- 500 × 4 = 2000 lumens
- The total light emitted is 2000 lumens

Conversion Definitions
Lux: Lux is the unit measuring illuminance, which means how much luminous flux falls on a surface area. It equals one lumen per square meter, describing the brightness perceived on that surface. Lux depends on both the intensity of light and the size of the area illuminated.
Lumens: Lumens quantify the total amount of visible light emitted by a source. It measures the light power perceived by the human eye, regardless of the direction or area it covers. Lumens indicate how bright a light source is, independent from distance or surface size.
Conversion FAQs
Can lux and lumens be directly compared without knowing the area?
No, lux and lumens measure different things; lux is lumens per square meter. Without knowing the surface area illuminated, you can’t convert lux to lumens directly because lumens depend on both lux and area.
What happens to lumens if the illuminated area increases but lux stays the same?
If lux remains constant and the area increases, the total lumens increases proportionally because lumens = lux × area. So, a larger surface illuminated with the same lux means more total lumens.
Why does converting 2400 lux to lumens require knowing the surface area?
Because lux measures light intensity per unit area, the total lumens depends on how big the surface is. Without the area, you only have brightness, not the total light quantity.
Can lumens be used to calculate lux for a known area?
Yes, to find lux from lumens, divide the total lumens by the area in square meters. Lux = lumens ÷ area. This gives light intensity per square meter.
Does the shape of the surface affect lux to lumens conversion?
The shape itself doesn’t affect the conversion directly, only the total area illuminated matters. However, irregular surfaces may cause uneven distribution, so measured lux could vary locally.
