The phot (symbol: ph) is a unit of illuminance that measures the amount of light received per unit area. Specifically, one phot is defined as one lumen per square centimeter. This measurement is crucial in fields such as photography, horticulture, and interior design, where understanding light levels is essential for optimal performance and aesthetics.
The phot unit is part of the CGS (centimeter-gram-second) system, which is a metric system of physical units. Although the phot is not commonly used in modern scientific literature, it serves as a historical reference point for illuminance measurement. The SI unit for illuminance is the lux, where 1 phot equals 10,000 lux.
The phot was introduced in the early 20th century as a means to quantify light levels in various environments. Over time, the need for a more standardized and universally accepted unit led to the adoption of the lux as the primary unit of illuminance in the International System of Units (SI). Despite this shift, the phot remains relevant for specific applications and historical context.
To convert illuminance from lux to phot, you can use the following formula: [ \text{Illuminance in phot} = \text{Illuminance in lux} \times 0.0001 ]
For example, if you have an illuminance level of 500 lux, the equivalent in phot would be: [ 500 \text{ lux} \times 0.0001 = 0.05 \text{ ph} ]
The phot is particularly useful in specialized fields such as:

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.
