About Picolux
The picolux (plx) equals 10⁻¹² lx. A theoretical subunit used only in precision photometric standard traceability. Even the faintest measurable natural illuminance - starlight on a moonless night at ~200 nlx - is 200 billion times brighter. Appears only in SI reference chains for calibration laboratories. 1 plx = 10⁻¹² lx.
About Lux
The lux (lx) is the SI coherent unit of illuminance, equal to 1 lm/m². Civil twilight outdoors: ~10 lx; dimly lit corridor: ~50 lx; typical office (EN 12464): 300-500 lx; operating theatre: ~1 000 lx. The most widely used illuminance unit in lighting standards worldwide. 1 lx = 1 lm/m².
