Phot
|
|
A phot is a photometric unit of illuminance, or luminous flux through an area.
It is not a metric (SI) unit.
Metric equivalent units:
<math>1\ ph = \frac{10000\ lumens}{meter^2} = \frac{10\ kilolumens}{meter^2}<math>
1 ph = 10000 lux = 10 kilolux
Metric dimensions:
illuminance = luminous intensity × solid angle / length2
