Conversion Formula
mlm = lm × 1000
About Lumens
The lumen (lm) is the SI derived unit of luminous flux, equal to 1 cd·sr. A standard wax candle emits approximately 12 lm total; a 40 W incandescent bulb about 450 lm; the common 800 lm LED lamp is the direct replacement for a 60 W incandescent. Defined since 2019 SI by fixing K_cd = 683 lm/W at 540 THz. 1 lm = 1 cd·sr.
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.
