Conversion Formula
klm = plm × 1.000000000e-15
About Picolumens
The picolumen (plm) equals 10⁻¹² lm. A sub-unit used only in precision optical metrology and photomultiplier calibration chains. Equivalent to the photometric output of a 555 nm monochromatic source radiating approximately 1.46 fW of radiant power. Below the sensitivity threshold of most photometric instruments without special cooling. 1 plm = 10⁻¹² lm.
About Kilolumens
The kilolumen (klm) equals 1 000 lm. High-efficiency LED light fittings: a modern 100 W-equivalent LED lamp emits 1.4-1.6 klm; a 100 W halogen PAR38 spot approximately 1.1 klm; short-throw projectors are rated at 1-5 klm (ANSI lumens). The standard unit for commercial LED fixture specifications and projector brightness. 1 klm = 10³ lm.
