About Nanolumens

The nanolumen (nlm) equals 10⁻⁹ lm. The scale of single-cell bioluminescence: an individual bioluminescent bacterium emits roughly 1-100 nlm; a luciferin-luciferase reaction in a single cell reaches the low-nanolumen range. Also the range for fiber-optic evanescent-wave sensors and fluorescence microscopy background levels. 1 nlm = 10⁻⁹ lm.

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.
