HImanshu_Sharmalamps have a borosilicate glass gas discharge tube (arc tube) containing solid sodium and a small amount of neon and argon gas Pennium mixture to start the gas discharge. The discharge tube may be linear (SLI lamp)Sodium Vapor Lamp Cite Note 1 or U-shaped. When the lamp is turned on it emits a dim red/pink light to warm the sodium metal and within a few minutes it turns into the common bright Yellow %28Colour%29yellow as the sodium metal Vaporizationvaporizes. These lamps produce a virtually monochromatic light averaging at a 589.3 nm wavelength (actually two dominant spectral lines very close together at 589.0 and 589.6 nm). As a result, the colors of illuminated objects are not easily distinguished since they are seen almost entirely by their reflection of this narrow bandwidth yellow light.
