High Pressure Sodium Vapor Lamp

The sodium vapor strikes an arc over 240 c.

High pressure sodium vapor lamp.

Low pressure and high pressure low pressure sodium lamps are highly efficient electrical light sources but their yellow light restricts applications to outdoor lighting such as street lamps where they are widely used. The principal difference between low and high pressure sodium lights is the operating pressure inside the lamp. High pressure sodium lights are used for illuminating large outdoor areas. When a mercury vapor lamp is first turned on it will produce a dark blue glow because only a small amount of the mercury is ionized and the gas pressure in the arc tube is very low so much of the light is produced in the ultraviolet mercury bands.

Typically these lights are used on sides of industrial buildings and in some street lamps. Set your store to see local availability. As the main arc strikes and the gas heats up and increases in pressure the light shifts into the visible range and the high gas pressure causes.

We also offer special conversion metal halide bulbs that can be used with fixtures intended for high pressure sodium light bulbs. In 1959 the development of polycrystalline alumina pca opened a new path to introduce the high pressure sodium vapor lamp as this material is very rarely affected by high pressure and temperature sodium vapor.

The high pressure sodium lamps have excellent colour rendition with a white colour appearance. High pressure sodium hps lamps are smaller and contain additional elements such as mercury and produce a dark pink glow when first struck and an intense pinkish orange light when warmed. Some bulbs also briefly produce a pure to bluish white light.
