About These Units
Kilolumen (klm)
A kilolumen (klm) equals 1,000 lumens. Used for powerful light sources: high-end projector 3-10 klm, car headlight 1-3 klm, stadium floodlight 20-100 klm, IMAX projector 30+ klm. Convenient for specifying commercial lighting installations.
Watt at 555nm (W@555nm)
Watts at 555nm represents the peak luminous efficacy of radiation: exactly 683 lumens per watt at 555nm wavelength (green-yellow light where human eye is most sensitive). This fundamental constant links radiometric (watts) to photometric (lumens) measurements.
