How can you tell if the halophane light you have is a metal halide or high pressure sodium?

If you have one or more of each type working, it is easy to tell the difference, a metal halide lamp produces a wide spectrum very white light, the high pressure sodium is a narrow spectrum light that is very yellow.
If you just have the light fixture, and need to know what kind of lamp it is made for, the lamp type is often mentioned on the ballast nameplate or a small sticker near the lamp socket. If that does not work, a metal halide ballast will usually be two pieces, a transformer with a heavy laminated metal core, and a capacitor in a silver can. The sodium lamp ballast will have these also, but in addition it will have a lamp striker in a second silver can, or a plastic module. In other words Metal Halide ballast: 2 pieces, HPSodium ballast: 3 components.

You can generally determine if a halophane light is metal halide or high pressure sodium by looking at the color of the light it emits. Metal halide lights produce a white or bluish-white light, while high pressure sodium lights emit a yellowish-orange light. Additionally, you can refer to the manufacturer's specifications or labels on the light fixture for more information.

Is halide granules being activated by light a chemical change?
No, the activation of halide granules by light is a physical change. Chemical changes involve the formation of new substances with different chemical properties. In this case, the halide granules are simply undergoing a change in their physical state or structure when exposed to light, rather than a change in their chemical composition.
What is the word equation of photographic film?
The word equation for photographic film is: Silver halide crystals + light → Silver metal + halide ions.
What is light metal?
Metal halide lights are a type of high-intensity discharge light. They're frequently used as grow lights for plants in conjunction with HPS (high pressure sodium) lights. MH lights are better for the earlier vegetative growth stages.
What part of the silver halide crystal is most affected by light when film is exposed?
The exposed silver halide crystal within the film is most affected by light during exposure. When light hits the crystal, it triggers a chemical reaction that forms a latent image, creating the basis for the eventual image development process.
What is the type of gas in an arc lamp?
The type of gas commonly used in an arc lamp is typically a noble gas such as xenon or mercury vapor. These gases are chosen for their ability to produce a bright and steady light when an electric current is passed through them in the lamp.
Will a metal halide light run a high pressure sodium lamp?
yes No Rafe, it will not. Remember when you tried it.
How do you ignite a 400w electronic metal halide or high pressure sodium bulb?
To ignite a 400W electronic metal halide or high pressure sodium bulb, you need to ensure that the power supply is connected and turned on. These bulbs require a ballast to regulate the electrical current, so make sure the ballast is functioning properly. Once everything is set up, simply turn on the power switch, and the bulb should ignite.
What are the different types of light?
Incandescent Lamps Light Emitting Diode Neon Lamps Fluorescent Tubes Compact Fluorescent Lamps Halogen Lamps Metal Halide Lamps High Intensity Discharge Lamps Low Pressure Sodium Lamps High Pressure Sodium Lamps
What is metal halide lighting?
Metal halide lighting is a type of high-intensity discharge (HID) lighting that produces light by passing an electric current through a mixture of mercury and metal halide gases. It is commonly used in commercial and industrial settings due to its high efficiency and bright, white light.
What type of light bulbs are in the street lights you see lighting streets in the city and on freeways?
They are most likely a type of metal halide bulb. <<>> The above answer bulb has a bright white light output. If the light output has an orange look about it then the bulb is a high pressure sodium lamp.
What is the difference between high pressure low pressure sodium lamps?
High pressure sodium lamps produce a brighter, more efficient light compared to low pressure sodium lamps. High pressure sodium lamps also have a longer lifespan and better color rendering properties. However, low pressure sodium lamps are more energy efficient and have a monochromatic yellow-orange light output.
How much electric current does it take to light a street lamp?
This varies greatly. A commonly used lamp is low pressure sodium (the very yellow ones). This would likely be 90w (but there are bigger and smaller) so 0.09 X 24 = about 2 kWH per day. The brighter yellow ones are high pressure sodium and would likely be about 150w (again there are bigger so maybe 250w or 400w). The newer white ones are metal halide and probably about the same power as a high pressure sodium with better light. You may find the odd mercury vapor light (white) in older fittings.
How much electrical current does it take to light up a street lamp?
This varies greatly. A commonly used lamp is low pressure sodium (the very yellow ones). This would likely be 90w (but there are bigger and smaller) so 0.09 X 24 = about 2 kWH per day. The brighter yellow ones are high pressure sodium and would likely be about 150w (again there are bigger so maybe 250w or 400w). The newer white ones are metal halide and probably about the same power as a high pressure sodium with better light. You may find the odd mercury vapor light (white) in older fittings.
Which light is brighter Metal Halide or mercury Vapor?
Metal Halide lights are generally brighter than mercury vapor lights. Metal halide lights produce a higher quality and more natural light, making them a popular choice for outdoor lighting in stadiums, parking lots, and other large commercial spaces. Mercury vapor lights tend to have a bluish-green tint and are less bright compared to metal halide lights.
Where can one buy high pressure sodium bulbs?
High pressure sodium light bulbs can be purchased at many retail locations. Some of these include Canadian Tire, Lowe's, Home Depot, and Rona. Acklands Grainger carries industrial high pressure sodium light bulbs as well.
Light given off by electric discharge through sodium vapor?
The light given off by electric discharge through sodium vapor appears as a bright yellow-orange color. This is because sodium vapor emits light in the yellow part of the spectrum when energized by an electric current. This phenomenon is utilized in street lamps and other high-intensity discharge lighting systems.
When photographic film is exposed to light the salt on the film breaks down what metal is formed?
The "salt" you are referring to is actually called silver-halide and are more commonly known as "silver salts". When silver-halide crystals are exposed to light, they form a compound known as "metallic silver"
