Elara Bennett2400 lux converts to 2400 lumens when the area is 1 square meter. This means, if the light is evenly spread over 1 m², the luminous flux is 2400 lumens.
Lux measures illuminance (light per unit area), while lumens measure total light output. To convert lux to lumens, multiply lux by the area in square meters. Without knowing the area, lux alone can’t directly convert to lumens, but assuming 1 m², they are equal.

Conversion Formula
To convert lux to lumens, you multiply the illuminance value by the surface area over which the light spreads. The formula is:
Lumens (lm) = Lux (lx) × Area (m²)
This works because lux measures how much light hits a surface per square meter, while lumens count the total light emitted. If you know the area, multiplying the lux by that area gives the total lumens.
Example: Given 2400 lux and an area of 1 m², lumens = 2400 × 1 = 2400 lumens.
Conversion Example
- Example 1: Convert 1500 lux to lumens over 2 m²:
- Multiply 1500 lux by 2 m².
- 1500 × 2 = 3000 lumens.
- The light source emits 3000 lumens for that area.
- Example 2: Convert 500 lux to lumens over 0.5 m²:
- Multiply 500 lux by 0.5 m².
- 500 × 0.5 = 250 lumens.
- This means the total light output is 250 lumens.
- Example 3: Convert 3200 lux to lumens over 1.5 m²:
- Multiply 3200 lux by 1.5 m².
- 3200 × 1.5 = 4800 lumens.
- So, the light emits 4800 lumens for that area.

You can read this chart by matching the lux value to the corresponding lumens value for a 1 square meter area. If the surface area changes, multiply lux by that area to find lumens.

Conversion Definitions
Lux: Lux is a unit measuring illuminance, quantifying how much light strikes a surface area. One lux equals one lumen per square meter. It indicates brightness as perceived over a certain space, useful for lighting design and measuring light intensity in environments.
Lumens: Lumens measure the total amount of visible light emitted by a source. It quantifies brightness independent of area, focusing on the total light output. Higher lumens mean brighter light sources, important for choosing bulbs or lighting equipment.
Conversion FAQs
Can I convert lux to lumens without knowing the surface area?
No, lux measures light per unit area, so without the surface area, you can’t accurately find total lumens. Lumens depend on total output, which is lux multiplied by area. Without area, the conversion is incomplete and gives no exact lumens value.
Why does 2400 lux equal 2400 lumens when area is 1 m²?
Because lux is lumens per square meter, when the area is exactly 1 m², the value in lux and lumens are the same numerically. Changing the area will scale lumens accordingly, but for 1 m², the two values match.
How does surface area influence the lux to lumens conversion?
Surface area directly affects the conversion. Lux measures brightness over an area, so larger areas multiply the lux value to find total lumens. For example, if area doubles, lumens double for the same lux level.
What if the light is unevenly distributed; can I still use the formula?
If light isn’t spread evenly, the formula gives an average estimate. Actual lumens in parts of the surface may vary. Detailed measurements or sensors are needed for precise conversions in non-uniform lighting.
Are there other units related to lux and lumens I should know?
Yes, candela measures luminous intensity in a specific direction, different from lumens total light output. Foot-candle is another illuminance unit used in some countries, equal to about 10.764 lux.
