About These Units
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.
Microlumen (μlm)
A microlumen (μlm) equals 10⁻⁶ lumens. Used in laboratory photometry, bioluminescence measurements (firefly: ~0.5 μlm/flash), and extremely dim light source characterization. Required precision instrumentation for measurement.
