phot
Definition: The phot (symbol: ph) is an illuminance unit equal to 1 lumen per square centimeter (10,000 lx). Measures high-intensity illumination.
History: Used in early 20th century photometry before SI standardization. From Greek 'phos' (light).
Current use: Mostly obsolete, but appears in some specialized scientific instruments and historical contexts.
lm/m²
Definition: The lumen per square meter (symbol: lm/m²) is equivalent to the lux (1 lx = 1 lm/m²). Measures luminous flux density.
History: Alternative name for lux used in some technical contexts to emphasize the lumen/m² relationship.
Current use: Used interchangeably with lux in lighting engineering and physics research papers.
