About Millilux
The millilux (mlx) equals 10⁻³ lx, also called 1 nox (CIE historical unit). Moonless clear sky: ~1 mlx; quarter moon: ~20-50 mlx; full moon at zenith: ~100-270 mlx. Minimum for dark-adapted outdoor navigation. Emergency exit pathway lighting is typically 1-5 mlx. 1 mlx = 10⁻³ lx = 1 nox.
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.
