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.
By utilizing the Lux Illuminance Unit Converter, you can enhance your understanding of lighting requirements, ensuring optimal conditions for various applications. For more information and to access the tool, visit our Lux Illuminance Unit Converter.
The lux-hour (lx·h) is a unit of measurement that quantifies the amount of light received over a period of time. It is derived from the lux, which measures illuminance, and is crucial for assessing lighting conditions in various environments. Understanding lux-hours is essential for architects, interior designers, and anyone concerned with optimal lighting.
The lux-hour is standardized under the International System of Units (SI). One lux is defined as one lumen per square meter, and when you multiply this by time in hours, you obtain lux-hours. This standardization ensures that measurements are consistent and universally understood, making it easier to compare lighting conditions across different settings.
The concept of measuring light dates back to the early 20th century when scientists began to understand the importance of light in various applications. The lux was officially defined in 1948, and since then, the lux-hour has evolved as a practical tool for measuring light exposure over time. This evolution has led to its widespread use in fields such as photography, agriculture, and health sciences.
To illustrate how to calculate lux-hours, consider a scenario where a workspace is illuminated with a light source providing 500 lux for 3 hours. The calculation would be as follows:
[ \text{Lux-Hours} = \text{Illuminance (lux)} \times \text{Time (hours)} ] [ \text{Lux-Hours} = 500 , \text{lx} \times 3 , \text{h} = 1500 , \text{lx·h} ]
This means that the workspace received a total of 1500 lux-hours of light during that period.
Lux-hours are particularly useful in various applications, including:
