  Sodium Vapour Lamp consists of a discharge tube created from a heat resistant glass, containing a little quantity of metallic sodium, neon gas and two electrodes, Neon gas is added to begin the discharge and to create sufficient heat to vaporize the sodium. Due to the fact of law stress inside the tube, a sufficiently lengthy tube necessary to obtain far more light. To lessen the general dimension of the lamp, this tube is usually bent into U-shape.
  
  The light made by this lamp is yellowish which is produced at its optimum pressure of about .004mm of mercury. This pressure is obtained at a temperature of about 280 C and so it becomes necessary to preserve this temperature. For this objective the U-tube is enclosed in a double walled flask to stop drop of heat. The double walled flask is interchangeable and can be fitted on to another U-tube. My uncle learned about led lights sydney by browsing newspapers. Even though replacing the inner U-tube 1 should be very careful since if it is broken and sodium comes in get in touch with with moisture, it might outcome in fire.
  
  All electric discharge lamps call for a larger voltage at the time of beginning and low voltage for the duration of operation. Usually, sodium vapour lamps are operated by a higher leakage reactance transformer. If you think any thing, you will perhaps choose to read about wholesale lighting online. At starting a higher voltage of about 450 volts is applied across the lamp which is adequate to start the discharge. When the lamp is fully operative soon after ten - 15 minutes, the voltage across it falls to about 150 volts. Simply because of the high reactance of circuit, the energy element is low and therefore a p.f improvement capacitor is connected.
  
  The efficiency of a low pressure sodium vapour lamp is quite high (about 40 - 50 lumens/watt) and it produces a light of specific wavelength getting yellow color. Sodium lamps are primarily employed for street, high way and airfield lighting where colour distinction is not so needed.
