Lux (lx) is the SI unit of illuminance, measuring the amount of light that falls on a surface per unit area. Specifically, one lux is defined as one lumen per square meter. This measurement is crucial in various fields, including photography, architecture, and horticulture, where understanding light intensity is essential for optimal outcomes.
The lux unit is standardized under the International System of Units (SI). It is widely recognized and utilized across various industries, ensuring consistency in measuring light levels. This standardization allows professionals to communicate effectively about lighting conditions, making it easier to design spaces that meet specific lighting requirements.
The concept of measuring light has evolved significantly over the years. The term "lux" was introduced in the early 20th century as part of the metric system. Before the adoption of lux, light intensity was often measured in foot-candles, which is still used in some regions. The transition to lux has provided a more precise and universally accepted method for measuring illuminance, facilitating advancements in lighting technology and design.
To illustrate how lux is calculated, consider a scenario where a light source emits 1000 lumens over an area of 10 square meters. The illuminance in lux can be calculated as follows:
[ \text{Illuminance (lx)} = \frac{\text{Total Lumens}}{\text{Area (m}^2\text{)}} ]
[ \text{Illuminance (lx)} = \frac{1000 \text{ lumens}}{10 \text{ m}^2} = 100 \text{ lx} ]
This calculation shows that the area receives an illuminance of 100 lux.
Lux is widely used in various applications, including:

1. What is lux in lighting?
Lux is the unit of illuminance that measures the amount of light that falls on a surface per square meter.
2. How do I convert lux to lumens?
To convert lux to lumens, multiply the lux value by the area in square meters. The formula is:
[ \text{Lumens} = \text{Lux} \times \text{Area (m}^2\text{)} ]
3. What is the difference between lux and foot-candle?
Lux is the metric unit of illuminance, while foot-candle is the imperial unit. One foot-candle is approximately equal to 10.764 lux.
4. How much lux is needed for a typical office?
A typical office environment requires around 300 to 500 lux for comfortable working conditions.
5. Can I use this tool for outdoor lighting calculations?
Yes, the Lux Illuminance Unit Converter can be used for both indoor and outdoor lighting calculations to ensure adequate illumination levels.

The lumen (symbol: lm) is the SI unit of luminous flux, a measure of the total quantity of visible light emitted by a source per unit of time. It quantifies the perceived power of light as it relates to human vision, making it an essential measurement in fields such as photography, lighting design, and architecture.
The lumen is standardized under the International System of Units (SI) and is defined based on the luminous efficacy of radiant energy. One lumen is equivalent to the light emitted by a uniform source of one candela over a solid angle of one steradian. This standardization ensures consistency in lighting measurements across various applications.
The concept of the lumen has evolved over time, with its origins tracing back to the early studies of light and vision. The term "lumen" was first introduced in the late 19th century as scientists sought to quantify light output in a way that was relatable to human perception. Over the decades, advancements in technology and a deeper understanding of photometry have led to the refinement of the lumen as a standard unit of measurement.
To illustrate the use of the lumen, consider a light bulb that emits 800 lumens. If you want to determine how many lumens are required for a room of 100 square feet to achieve a recommended illuminance level of 50 lux, you would calculate it as follows:
The lumen is widely used in various applications, including:
