Conversion Formula
µlm = lm × 1000000
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 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.
