      What's The Upside to Low (LPS) and High Pressure (HPS) Sodium Lights:

      Sodium vapor lighting has been around since the middle of the 20th century (in commercial production since the 1930s) and it generally represents a high efficiency way to provide lighting over a vast area. Sodium lights operate in a range where the human eye is very sensitive and so there is less power required to achieve the same lighting effect. For this reason they are very efficient. Additionally, despite their long warm-up period (5-10 minutes), low pressure sodium lamps will re-ignite immediately in the event of a power interruption. It is particularly useful for outdoor lighting where energy efficiency is at a premium (such as with municipalities lighting the streets or other common areas like parking lots. LPS and HPS lights are much more efficient as well as longer lasting than incandescent bulbs, many fluorescent bulbs, and most high intensity discharge lamps in general.


      Advantages

      Low Pressure Sodium light has a number of very unique properties arising from its spectral output, many of which make it technically the most suitable light source for road lighting and these are covered in detail on the next page. In addition, the large physical size of the lamp means that it has a low surface luminance so it is less likely to give rise to glare, and the low operating temperature permits the use of compact optical systems and lightweight plastic lanterns. They are the favoured light sources for tunnel illumination, particularly in Japan and Korea where underground roads extending 10 miles or more are not unusual. The long lamps may be aligned end-to-end to produce a continuous line of light and this almost totally eliminates the stroboscopic effect of driving past high brightness lights at speed. Driver fatigue is drastically reduced there is a well proven link between low pressure sodium lighting and reduced accident rates in tunnels. Fluorescent lamps also lend themselves well to this application, but SOX offers a more energy efficient solution.


      Furthermore, the lamp itself is relatively inexpensive and can be operated on low cost electrical control gear. Of increasing significance is the fact that it contains zero mercury, and can be easily disposed of as non-toxic waste without incurring extra expense at its end of life. Most high pressure sodium and all other light sources employed in street lighting contain mercury and special restrictions apply to the disposal of used lamps. A final advantage is that in the case of a momentary power supply interruption, the lamp will restrike as soon as the power is restored and no cooling down period is required.


      The burning position is generally confined to the horizontal position ±20°. Greater inclinations can result in the liquid sodium running down to the lower end of the lamp with the result that the upper part of the lamp becomes depleted of sodium vapour and efficacy is lost. Vertical burning is permitted only for the low wattage lamps, but only with the cap uppermost. Illumination with the cap down would cause an accumulation of sodium behind the electrodes, and the glass-to-metal seals in this region are a weak point which can fail in the presence of excess sodium.
