Lux per hour (lx/h) is a unit of measurement that quantifies the amount of illuminance received over a specified period. It is derived from the lux, which measures luminous flux per unit area. This metric is crucial for evaluating lighting conditions in various environments, ensuring that spaces are adequately illuminated for safety and comfort.
The lux is standardized by the International System of Units (SI), where 1 lux equals 1 lumen per square meter. Lux per hour, therefore, represents the total illuminance received over the course of an hour, making it a valuable metric for assessing lighting efficiency and energy consumption.
The concept of measuring light intensity has evolved significantly since the early days of photometry. Initially, light was measured using candles and other rudimentary sources. The introduction of the lux as a standard unit in the 20th century marked a significant advancement in the field of lighting design and engineering, allowing for more precise calculations and comparisons.
To illustrate the use of lux per hour, consider a room with an illuminance of 300 lux. If the lights are on for 5 hours, the total illuminance received would be calculated as follows:
Lux per hour is commonly used in various fields, including architecture, photography, horticulture, and workplace safety. It helps professionals determine the adequacy of lighting in different settings, ensuring compliance with safety standards and enhancing productivity.
To use the lux per hour tool effectively, follow these steps:
What is lux per hour (lx/h)? Lux per hour is a measurement of the total illuminance received over a specified time, expressed in lux multiplied by hours.
How do I convert lux to lux per hour? To convert lux to lux per hour, multiply the lux value by the number of hours the light is on.
What is the significance of measuring lux per hour? Measuring lux per hour helps assess the adequacy of lighting in various environments, ensuring safety and comfort.
Can I use lux per hour for outdoor lighting assessments? Yes, lux per hour is applicable for both indoor and outdoor lighting assessments, helping to ensure adequate illumination in all settings.
How can I improve my lighting efficiency based on lux per hour calculations? By analyzing lux per hour values, you can identify areas where lighting can be reduced or optimized, leading to energy savings and improved lighting quality.

A footcandle (fc) is a unit of illuminance that quantifies the amount of light that falls on a surface. Specifically, one footcandle is defined as the illuminance produced by a uniform light source of one candela at a distance of one foot. This measurement is crucial in various fields, including photography, architecture, and horticulture, where precise lighting conditions are essential for optimal performance.
The footcandle is part of the Imperial system of measurement and is commonly used in the United States. It is standardized by the International System of Units (SI), which allows for consistent and reliable measurements across different applications. Understanding footcandles is vital for professionals who need to ensure adequate lighting in workspaces, classrooms, and public areas.
The concept of measuring light has evolved significantly since the early days of photography and film. The footcandle emerged as a practical unit in the early 20th century, providing a standardized way to discuss and measure light levels. Over time, advancements in lighting technology and a deeper understanding of human vision have led to more refined methods of measuring illuminance, including the use of lux, which is the metric equivalent of footcandles.
To illustrate how to convert footcandles to lux, consider a scenario where a room is illuminated with a light source that produces 50 footcandles. To convert this to lux, you can use the conversion factor: 1 footcandle = 10.764 lux. Therefore, 50 fc x 10.764 = 538.2 lux.
Footcandles are widely used in various industries, including:
To effectively use the footcandle tool available at Inayam's Illuminance Converter, follow these steps:
What is a footcandle? A footcandle is a unit of illuminance that measures the amount of light falling on a surface, defined as one lumen per square foot.
How do I convert footcandles to lux? To convert footcandles to lux, multiply the footcandle value by 10.764. For example, 10 fc equals 107.64 lux.
Why is footcandle important in photography? Footcandles help photographers determine the appropriate lighting conditions for capturing images, ensuring optimal exposure and clarity.
What are the recommended footcandle levels for office spaces? The recommended footcandle levels for office spaces typically range from 30 to 50 fc, depending on the tasks being performed.
Can I use the footcandle tool for outdoor lighting? Yes, the footcandle tool can be used to measure outdoor lighting conditions, helping you assess the adequacy of illumination for safety and aesthetics.
By utilizing the footcandle tool effectively, you can ensure that your lighting conditions meet the necessary standards for various applications, ultimately enhancing your projects and improving user experience. For more information and to access the tool, visit Inayam's Illuminance Converter.
