About Nanolux
The nanolux (nlx) equals 10⁻⁹ lx. Astronomical night-sky scale: the zodiacal band contributes ~10-50 nlx; airglow ~150 nlx; the Milky Way core ~100 nlx. The absolute human eye threshold is around 100 nlx. Used in night-sky quality metrics and photomultiplier tube calibration. 1 nlx = 10⁻⁹ 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.
