Elara Bennett35 lux converts to 35 lumens per square meter on a surface area of one square meter. Because lux measures illuminance, and lumens quantifies luminous flux, converting directly depends on the area lit.
Lux is lumens divided by area, so to convert lux to lumens, you multiply lux by the area in square meters. Without knowing the surface area, converting lux to lumens is incomplete. Assuming an area of 1 square meter, 35 lux equals 35 lumens.

Conversion Formula
The relationship between lux and lumens depends on the surface area illuminated. Lux (lx) is defined as lumens per square meter (lm/m²). To convert lux to lumens, multiply the illuminance by the area:
Lumens = Lux × Area (in m²)
This works because lux measures how spread out the light is over a surface, while lumens measure the total light emitted or received.
Example:
- Given: 35 lux and an area of 1 m²
- Calculation: 35 lx × 1 m² = 35 lumens
- If the area was 2 m²: 35 lx × 2 m² = 70 lumens
Conversion Example
- Convert 50 lux over 2 m²:
- Multiply: 50 × 2 = 100 lumens
- The light source emits 100 lumens over that area.
- Convert 20 lux over 0.5 m²:
- Multiply: 20 × 0.5 = 10 lumens
- Lower area means fewer lumens for same lux.
- Convert 45 lux over 3 m²:
- Multiply: 45 × 3 = 135 lumens
- More area, more total lumens needed.
- Convert 15 lux over 4 m²:
- Multiply: 15 × 4 = 60 lumens
- Illuminance times surface gives total lumens.

Conversion Definitions
Lux: Lux measures illuminance, the amount of visible light that falls on a surface, per unit area. It equals one lumen per square meter, quantifying how bright the light appears to human eyes on that surface.
Lumens: Lumens quantify luminous flux, the total amount of visible light emitted by a source. It describes the perceived power of the light, independent of how that light is spread over an area.
Conversion FAQs
Is it possible to convert lux to lumens without knowing the surface area?
No, lux measures light intensity per square meter, so without knowing the actual surface area where light is distributed, you cannot find the total lumens. Lumens depend on total light output, lux depends on area illuminated.
Why does the area affect lux to lumens conversion?
Because lux equals lumens divided by area, changing the surface area changes how concentrated the light is. Larger areas with same lumens produce lower lux, smaller areas produce higher lux for same lumens.
Can lumens be higher than lux in a conversion?
Yes, lumens are total light output, lux is intensity per unit area. For areas greater than 1 m², lumens will be higher than lux value. They measure different aspects, so direct comparison without area is misleading.
Does converting lux to lumens change with different light sources?
Conversion depends on area, not light source type. However, different light sources emit lumens differently, so measured lux for same lumens can vary depending on beam spread and distance.
How accurate is assuming 1 m² area when converting 35 lux to lumens?
Assuming 1 m² is a simplification for easy conversions. Real-world surfaces vary, so actual lumens might be higher or lower. For precise results, measure or estimate the exact area illuminated.
