Brightness, represented by the symbol br, is a measure of the amount of light that is emitted or reflected from a surface. It is often quantified in terms of illuminance, which refers to the amount of luminous flux per unit area. This measurement is crucial in various fields, including photography, architecture, and lighting design, as it helps determine how well-lit a space is.
Brightness is standardized using units such as lux (lx) and foot-candle (fc). One lux is defined as one lumen per square meter, while one foot-candle is equivalent to one lumen per square foot. Understanding these units is essential for accurately measuring and converting brightness levels in different environments.
The concept of brightness has evolved significantly over time. Early measurements were based on subjective assessments of light intensity. However, with advancements in technology and the development of photometric standards, brightness is now measured using precise instruments. The introduction of digital light meters has further enhanced our ability to quantify brightness accurately.
To illustrate how to convert brightness levels, consider a scenario where you have a light source emitting 1000 lumens over an area of 10 square meters. The illuminance can be calculated as follows:
[ \text{Illuminance (lux)} = \frac{\text{Luminous Flux (lumens)}}{\text{Area (m²)}} ]
[ \text{Illuminance} = \frac{1000 \text{ lumens}}{10 \text{ m²}} = 100 \text{ lux} ]
Brightness measurements are vital in various applications, including:

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.
