In my experience (northeast USA) most HIGH PRESSURE SODIUM street lights are 150 watt or 250 watt For example in NYC 250 watts is used at intersections and 150 watt everywhere else
By the colour of the light that they emit. Sodium vapour lamps produce yellow/orange light while Mercury vapour lamps produce white light.
Sodium vapor lamps are commonly used for outdoor lighting, such as street lighting, parking lots, and sports arenas, due to their high efficiency and long lifespan. They are also used in horticulture to promote plant growth and in industrial settings for high-intensity lighting requirements.
Argon gas is used in sodium vapor lamps to provide the starting mechanism for the lamp. When the lamp is turned on, the argon gas helps facilitate the initial discharge of electricity through the lamp. Neon gas is used to help improve the color rendering of the lamp, making the light emitted appear more natural and pleasant.
No, washing soda is a hydrated form of sodium carbonate, Na2CO3.10H2O and this generally loses water, effloresces, as the vapour pressure of the salt is usually greater than the vapour pressure of water in the surrounding air. Deliquescence is taking in water from the atmosphere.
In a low pressure sodium vapour lamp, argon or neon gas is first heated up to emit a slight red or purple glow. The heat from this warms sodium metal in the light to the point of vaporizing, which is when the familiar yellow glow begins.
Sodium vapour.
Sodium-vapour lamp, electric discharge lamp using ionized sodium,
no
Sodium is used for loads of things! Sodium Chloride is table salt, sodium metal is used to prepare elements to make alloys, and sodium vapour is used in street lights. It is also key in the paper, glass and textile industry. Hope this Helps!!

Sodium lighting is more efficient to run than white lights, and it gives an even light with less glare.

water vapour
Probably sodium.
Sodium lamp
No, sodium and mercury exist as diatomic molecules in the vapour state due to the nature of their chemical bonding. Sodium forms Na2 while mercury forms Hg2 molecules.
