Conversion Formula

µlm = mlm × 1000

About Millilumens

The millilumen (mlm) equals 10⁻³ lm. The output range for typical LED indicator packages: a standard 5 mm through-hole LED at 20 mA produces 10-200 mlm depending on color and efficiency. Small wearable health-monitor LEDs and remote-control emitter LEDs operate in this range. 1 mlm = 10⁻³ lm.

About Microlumens

The microlumen (µlm) equals 10⁻⁶ lm. LED indicators in deep-sleep power-save mode, fiber-optic signal pilots, and OLED display pixels at minimum brightness fall into this range. Equivalent to a 555 nm source radiating approximately 1.46 nW of radiant power. A night-vision display backlight operates at 1-100 µlm. 1 µlm = 10⁻⁶ lm.
