What is a Low Pressure Sodium Light:

Low Pressure Sodium Vapor (LPS) lights are a specific type of gas-discharge light. The bulb principally contains solid sodium metal inside a borosilicate glass tube that vaporizes once the lamp is turned on. During start (while the sodium is still in solid form) the lamp emits a dim reddish/pink glow. Once the metal is vaporized the emissions become the characteristic bright yellow associated with sodium vapor lamps. The spectrum of visible emissions from an LPS light is actually very close together (589 and 589.6 nm, virtually monochromatic) resulting in the colors of illuminated objects being nearly indistinguishable.


Basic Characteristics

The reason for the remarkably high efficacy of the low pressure sodium discharge is not so much because its discharge converts electrical energy into visible light particularly efficiently, moreover it is due to the fact that the wavelength of light it radiates happens to be very close to the peak sensitivity of the human eye under normal viewing conditions. Figure S2 shows the energy balance of a typical low pressure sodium lamp, which reveals that in fact only about 30% of the input power is converted into visible light. This percentage is comparable with other modern discharge lamps. Figure S3 meanwhile illustrates its spectrum superimposed on the sensitivity curve of the human eye, which shows the proximity of its radiation to the most effective wavelengths.


The lamp has been subjected to continual improvements in materials and manufacturing technology over the years, which has allowed it to unfailingly maintain its position as the most efficient light source available. Figure S4 illustrates the elevating efficacy of each of the principal light source technologies over time, and there is no technical reason why low pressure sodium should stop here. Whether or not manufacturers find it commercially interesting to make the necessary investments in further improvements is another matter however! That fact alone is responsible for the flattening of the LPS line since the 1990s, when all further research on this technology effectively ceased.
