• Astronomers measured the starlight in milliluxes to study faint celestial objects.
• The security system required at least 100 milliluxes of ambient light to function properly.
• Night vision equipment can operate in conditions of just a few milliluxes.
• The laboratory's dark room maintained illumination levels below 1 millilux for sensitive experiments.
