5500 Lux to Lumens – Full Calculation Guide

5500 lux corresponds to 5500 lumens when the illuminated surface area is 1 square meter. This direct equivalence happens because lux measures luminous flux per unit area, so for 1 square meter, lux and lumens are numerically equal.

Lux is a measure of illuminance, defined as lumens per square meter. When converting lux to lumens, multiplying the lux value by the surface area in square meters gives the total luminous flux in lumens. Without knowing the area, lux cannot be converted uniquely to lumens.

Conversion Formula

The formula to convert lux to lumens depends on the surface area illuminated:

Lumens = Lux × Area (in square meters)

Lux measures how much luminous flux falls on a surface per unit area. Lumens measure total visible light emitted. To find lumens from lux, multiply the lux value by the area that the light shines on.

For example, if you have 5500 lux on a 1 m² surface:

  • Lux = 5500 lx
  • Area = 1 m²
  • Lumens = 5500 × 1 = 5500 lm

If the area was 2 m² instead:

  • Lumens = 5500 × 2 = 11000 lm

Conversion Example

  • Convert 3200 lux on a 0.5 m² surface to lumens:
    • Multiply lux by area: 3200 × 0.5 = 1600 lumens
    • This means 1600 lumens of light falls on the 0.5 m² area
  • Convert 10000 lux on a 2 m² surface:
    • 10000 × 2 = 20000 lumens
    • Higher lux or bigger area increases total lumens
  • Convert 450 lux on 0.8 m² area:
    • 450 × 0.8 = 360 lumens
    • Smaller area or lower lux lowers total lumens
  • Convert 7500 lux on 1.2 m²:
    • 7500 × 1.2 = 9000 lumens
    • Both lux and area affects lumens value
  • Convert 2000 lux on 3 m²:
    • 2000 × 3 = 6000 lumens
    • Doubling area triples lumens here

Conversion Definitions

Lux: Lux is measure of illuminance, representing how much luminous flux falls onto a surface per square meter. It quantifies brightness perceived on a surface, expressed as lumens per square meter. Lux values vary with distance and area illuminated.

Lumens: Lumens quantify the total amount of visible light emitted by a source. It indicates the brightness emitted in all directions, independent of distance or surface area. Lumens measure light output, while lux measures light received per area.

Conversion FAQs

Can lux be converted to lumens without knowing the surface area?

No, lux measures luminous flux per unit area, so without knowing the illuminated area, lumens cannot be calculated uniquely. Lumens equal lux multiplied by the area. Without area, conversion is incomplete and ambiguous.

Why does 5500 lux equal 5500 lumens only for 1 square meter?

Because lux is lumens per square meter, if the surface area is exactly 1 m², the numeric value of lux and lumens are equal. For any other area, lumens = lux × area, changing the relationship.

Does changing the distance from a light source affect lux and lumens equally?

Distance affects lux because illuminance decreases with distance squared, but lumens emitted by the source remains constant. So lux changes with distance, while lumens stay the same.

How precise is converting lux to lumens using this formula?

The formula lumens = lux × area gives exact total luminous flux on the surface, assuming uniform light distribution and accurate area measurement. Irregular surfaces or uneven lighting can cause real values to differ.

What practical use is converting lux to lumens?

This conversion helps in lighting design and measurement, allowing comparison between light intensity (lux) and total light output (lumens) depending on room size or surface area illuminated.
