Unit daph
Name decaphot
Category Illuminance
Details A decaphot (daph) is a unit of illuminance used in the field of photometry, which refers to the measurement of light. The term "illuminance" describes the amount of light that falls on a surface. The decaphot is derived from the phot, another illuminance unit. One decaphot is equal to 10 phot or 10,000 lux.

In photometry, the phot is the standard unit used to measure illuminance or the amount of light on a surface. The unit is named after the Greek word "phōs" meaning light, and one phot represents an illuminance of one lumen per square centimeter. The term "lux" is also commonly used as a unit of illuminance and is equal to one lumen per square meter.

A daph is used when larger quantities of light need to be measured, such as illuminance levels in stadiums or outdoor spaces with a high density of lighting fixtures. It is not as commonly used as the phot or lux, but it can still help to simplify and standardize illuminance measurements in certain situations where a larger unit is more practical.
