About Megalux
The megalux (Mlx) equals 10⁶ lx. Reached only by extreme short-range sources: a short-arc xenon lamp at 5 cm produces ~1-10 Mlx; pulsed photographic strobes at close range several Mlx. The full solar disc on Earth's surface gives ~100 klx - far below 1 Mlx. 1 Mlx = 10⁶ lx.
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.
