Technical Information

High pressure sodium (HPS) lamps do contain mercury. They produce a dark pink glow when first ignited, and reach a pinkish orange light when the are fully lit. A few bulbs will produce a pure to bluish white light when warming up. This will be from the mercury when the lamp is in mid-phase. The sodium elements is the main source of light from the HPS lamp, and it is put under extreme pressure to broadened the high sodium pressures in the lamp; because of this broadening and the output from mercury, the colors of items under these light bulbs can be distinguished.

High pressure sodium light bulbs are very efficient. They mainly used for many streetlights and outdoor security lighting. Understanding the change in human spectrum vision sensitivity is needed for proper planning when designing lighting applications. There is a lot of high chemical activity of the high pressure sodium arc tube, which is typically made of translucent aluminum oxide This HPS arc tube led GE call their high pressure sodium lamps "Lucalox".

High-pressure sodium lamps end of life will cycle and it is because a loss of sodium in the bulb. Sodium is very reactive element. HPS lamps can be ignited at a relatively low voltage but as they warm up it will cause the internal gas pressure within the bulb and increased voltage is needed to maintain the arc discharge. When the lamp gets older, the required voltage for the arc will exceed the output generated by the HPS ballast. The High Pressure Sodium lamp will heat up where the arc-tube fails and the light bulb will burn out.
