Materials

NameColor
For dielectrics (non-metals), this specifies diffuse reflectance for opaque materials, or transmission color for transparent materials.
For conductors (metals), this specifies reflection color.

Light Sources

NameIntensity
Luminous flux is measured in lumen (lm) and is the quantity of light emitted by a source.

Illuminance is measured in lux (lx) and is the measure of light quantity that hits a surface.

Luminance is measured in candelas per square meter (cd/m²) and is the measure of light that is emitted from a surface.

Radiant flux is measured in watts (W) and is the radiant energy emitted by a source.

Irradiance is measured in watts per square meter (W/m²) and is the radiant energy received by a surface.
