Elara Bennett60 lux corresponds to 60 lumens per square meter, but converting lux to lumens requires knowing the area illuminated. Assuming an area of 1 square meter, 60 lux equals 60 lumens.
Lux measures illuminance, how much light falls on a surface per unit area, while lumens measure total light output. To convert lux to lumens, multiply lux by the surface area in square meters. Without the area, lux alone can’t be directly converted to lumens.

Conversion Formula
The conversion from lux to lumens depends on the area over which the light is spread. Lux (lx) is lumens per square meter (lm/m²), so the formula is:
Lumens (lm) = Lux (lx) × Area (m²)
This works because lux measures how many lumens fall on every square meter. If you know the size of the surface, multiplying lux by that area gives total lumens hitting it.
Example:
- Given 60 lux over 2 square meters
- Lumens = 60 lx × 2 m² = 120 lumens
Conversion Example
- Convert 45 lux on 3 square meters:
- Multiply lux by area: 45 × 3 = 135 lumens
- The surface receives 135 lumens in total
- Convert 75 lux on 1.5 square meters:
- 75 × 1.5 = 112.5 lumens
- This is the total luminous flux on that surface
- Convert 55 lux on 4 square meters:
- 55 × 4 = 220 lumens
- Meaning 220 lumens light hits the entire area
- Convert 80 lux on 0.8 square meters:
- 80 × 0.8 = 64 lumens
- The total light energy is 64 lumens

The chart shows how lux values convert to lumens assuming the area is exactly 1 square meter. To use it for other areas, multiply the lumen value by your surface size. For example, 50 lux on 3 m² equals 150 lumens.

Conversion Definitions
Lux: A unit measuring illuminance, lux quantifies how much luminous flux hits a surface area. One lux equals one lumen per square meter. It tells you how bright a surface appears, important for lighting design and visibility assessment.
Lumens: Lumens measure the total amount of visible light emitted by a source. Unlike lux, it doesn’t depend on area but rather total light output. Higher lumens mean brighter light, useful when comparing bulbs or lamps.
Conversion FAQs
Why does lux depend on area but lumens do not?
Lux measures light intensity on a surface, so it depends how spread out light is over that area. Lumens count all light emitted regardless of where it lands, so area doesn’t affect lumens directly. You need area to relate lux and lumens.
Can 60 lux be converted to lumens without area information?
No, lux alone can’t give lumens without knowing surface area. Lux is lumens per square meter. So without area, the total lumens can’t be found. If you assume 1 square meter, then lux equals lumens, but that may not be true for bigger or smaller areas.
What if light isn’t evenly distributed when converting 60 lux to lumens?
Uneven light makes conversion trickier. Lux measures average light per area, but actual lumens depend on how light spreads. You’d need to measure lux at different spots or use total lumens from the light source instead of calculating from lux values.
How is this conversion useful in real life?
Knowing how to convert lux to lumens helps when planning lighting for rooms or outdoor spaces, ensuring enough light reaches surfaces. It’s important for architects, electricians, and designers to match light output with required brightness levels.
Does changing the distance from a light source affect lux and lumens?
Distance changes lux because light spreads out, lowering intensity on surfaces farther away, but lumens emitted by the source stays the same. So lux decreases with distance, lumens remain constant, showing why area and position matter in conversion.
