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 Kilolux
The kilolux (klx) equals 1 000 lx. Outdoor daytime scale: overcast sky ~10-20 klx; direct mid-latitude sunshine at noon ~80-100 klx. Required for fine inspection work, surgery, and color-critical print evaluation (ISO 3664: 2 klx). Also the range for plant-growth LED systems at canopy level. 1 klx = 10³ lx.
