Sunlight is composed of a broad spectrum of colors, whereas light from a sodium vapor lamp is nearly monochromatic, typically emitting a very narrow range of wavelengths centered around the yellow part of the spectrum. This is due to the specific electronic transitions of sodium atoms, which do not produce the broad spectrum seen in sunlight.
