Converting 000 lux to lumens results in 0 lumens.
Lux measures illuminance, which is the amount of light falling on a surface per unit area, while lumens measure the total light output emitted by a source. Since 000 lux is zero, the total lumens corresponding is also zero, because no light is illuminating the surface.

Conversion Formula
The conversion from lux to lumens depends on the surface area receiving the light. Lux (lx) is lumens per square meter (lm/m²). To find lumens (lm) from lux, you multiply lux by area (in m²):
Lumens = Lux × Area
This formula works because lux measures how much light hits every square meter. So, if you know how many lux the surface has and how big the surface, multiplying them gives total lumens falling on that surface.
For example, if 10 lux is shining on an area of 2 m²:
- Lux = 10 lx
- Area = 2 m²
- Lumens = 10 × 2 = 20 lm
Conversion Example
- Example 1: Convert 50 lux on 3 m²
– Multiply 50 by 3
– Result: 150 lumens
– Explanation: The light intensity over the surface is 50 lux, so total light is 150 lumens. - Example 2: Convert 100 lux on 0.5 m²
– Multiply 100 × 0.5
– Result: 50 lumens
– Explanation: Smaller area means fewer total lumens despite high lux. - Example 3: Convert 0 lux on any area
– Multiply 0 × any area
– Result: 0 lumens
– Explanation: No light means no lumens regardless of area. - Example 4: Convert 25 lux on 4 m²
– Multiply 25 × 4
– Result: 100 lumens
– Explanation: Moderate light over bigger surface. - Example 5: Convert 10 lux on 10 m²
– Multiply 10 × 10
– Result: 100 lumens
– Explanation: Low lux but very large surface area increases lumens.

This chart assumes a surface area of 1 square meter for simplicity. To use it, multiply your lux value by the area in square meters to get lumens. Negative lux values don’t physically make sense but included here for completeness of range.

Conversion Definitions
Lux: Lux is a unit measuring illuminance, representing how much luminous flux spread over a square meter of surface. It tells how bright a surface appears when light falls on it, combining both the intensity and area involved in lighting.
Lumens: Lumens measure the total amount of visible light emitted by a source. It quantifies brightness as perceived by the human eye, independent from area, showing the absolute light output from lamps, LEDs, or other lighting devices.
Conversion FAQs
Can lux be negative when measuring light intensity?
Lux values cannot be negative in practical terms because illuminance measures light falling on surfaces. Negative lux might appear in calculations or sensor errors, but physically it means no light or zero lux.
Why does converting 000 lux always give zero lumens?
Because lux measures light per area, zero lux means no light hitting the surface. Multiplying zero by any area results zero lumens, indicating no total light output onto that area.
Does the surface area affect lux measurement directly?
Lux is light per unit area, so it depends on how much light falls on each square meter, not total surface area. However, lumens depend on both lux and area, so bigger surfaces with same lux have higher lumens.
How to convert lux to lumens if surface area is unknown?
Without knowing surface area, lumens can’t be accurately calculated from lux alone because lumens = lux × area. You must measure or estimate the surface size to convert correctly.
Is it possible for the same lumens to have different lux values?
Yes, lumens spread over different areas produce different lux. For example, 100 lumens concentrated on 1 m² gives 100 lux, but spread over 10 m² gives only 10 lux.
