Learn About The Functionality Of High Pressure Sodium Lights And Insights On How These Types Of Lamps Can Be Quite Efficient

The high pressure sodium lights are relatively small and contain extra element mercury. On first struck dark pink color glow is produced and once it gets further heated it grows into pinkish orange. Some times in between a bluish while glow is also made as a result of the mercury present inside when the sodium is not completely warmed.

The D line of sodium is responsible for the generation of light from the lamp, which is extremely pressurized broadened by the high pressure of sodium. This broadened and mercury emission results in distinctive vision under the lamp. Thus it can be employed in spots whereby color rendering is a very important element. Thus sodium lamps are utilized by indoor gardeners thanks to vast span color temperature spectrum at much cheaper cost. Due to the excessive high chemical reactivity of the sodium arc inside the lamp it is excursively composed of Aluminum oxide layer to preserve it from deprivation. A noble gas Xenon is treated into the lamp which acts as a starter gas. It do not interfere with reactions taking place inside the lamp, and helps the lamp to get started at relatively lower potential yet itself remains to be inactive and unchanged and so acts as catalyst.

Generally there are three modes of operation of high pressure sodium lamps:-

- Lamp is switched off, when no current flows.
- Lamp is working when liquid amalgam is situated in the tube.
- Lamp is working when the full amalgam has evaporated.

The performance of sodium lamp is 50 to 140 lumen/watt that is definitely much more than mercury lamps. High pressure sodium light causes relatively very lower pollution compared to mercury vapor lamp. Thereby high pressure sodium lights are not only significantly more productive and useful than other modes of light but are also eco friendly in nature. So, we should welcome this new invention with warm hands.
