Why sodium Vapour lamps are used in street lights?

Sodium-vapour lamp, electric discharge lamp using ionized sodium, used for street lighting and other illumination. When current passes between the electrodes, it ionizes the neon and argon, giving a red glow until the hot gas vaporizes the sodium. The vapourized sodium ionizes and shines a nearly monochrome yellow.

How does a sodium Vapour lamp work?

The HPS lamp consists of a narrow arc tube supported by a frame in a bulb. The arc tube has a high pressure inside for higher efficiency. The arc then heats up the mercury and the mercury vapor then lights, giving the lamp a bluish color. The lamp heats and the sodium is the last material to vaporize.

What are the advantages of sodium Vapour lamp?

WHAT ARE THE ADVANTAGES OF SODIUM VAPOUR LAMPS OVER OTHER LAMPS? Efficiency: Sodium Vapour Lamps are very efficient, turning one watt of power into a whopping 200 lumens! Compare this with the 12 lumens per watt of an incandescent bulb, or the 60 lumens per watt of a CFL, or the 90 lumens per watt of FTL.

When a sodium vapor lamp is switched on initially the color is?

(D) 112 volts. (D) Blue. (D) krypton gas. (D) high leakage reactance….

Which combination of gas is filled in a lamp and resulting color is incorrect?

Which of the following combination of gas is filled in lamp and the resulting color is incorrect? (D) Magnesium-white.

Can I use 60W LED bulb in a 40W socket?

Yes, you can use it! A 60-watt equivalent LED bulb uses around 8 watts on average. That’s 5X less than a 40-watt incandescent.

Why do lamps have wattage limits?

A light fixture’s maximum wattage often reflects how much power can go through before the wires get overwhelmed by the current and fail (i.e. start smoking or burn up). If a fixture is rated for a maximum of 60 watts, then it’s dangerous to exceed that.

Can I use a 9 watt LED in a 40 watt lamp?

Yes. The fixture is concerned with heat. Your LED light bulb makes about 9 watts of heat. Your fixture is rated for a bulb that makes 40 watts of heat.

What is the equivalent of a 25 watt bulb in LED?

Compare wattage

Traditional bulb1 Halogen2 LED
25 watts 15 watts 2 watts
40 watts 25 watts 5 watts
60 watts 40 watts 7 watts
75 watts 45 watts 9 watts

Can I put a higher watt LED bulb in my lamp?

When it comes to replacing old incandescent bulbs with LEDs, a common question that customers ask is: “Can I use an LED bulb that has a higher wattage equivalent than my fixture allows?” The simple answer is yes, as long as the LED bulb uses less wattage than your fixture.
