High Intensity Discharge (HID) lamps are a type of arc lamp. An HID lamp is comprised of a "glass" arc tube filled with a gas and a metal salt. The tube is generally fitted with two tungsten electrodes. Current applied to the electrodes is initially conducted in an arc through the gas. This initial arc raises the temperature of the metal salt until it vaporizes. At this point, the arc is conducted by the vaporized salt, greatly increasing the light output and decreasing the electrical current consumed.
There are several types of HID lamps in current use:
Mercury-vapor
Metal-halide (MH)
Ceramic MH
Low Pressure Sodium-vapor
High Pressure Sodium-vapor
Xenon short-arc
Each chemistry offers a different mix of operating characteristics including light intensity, color temperature, color rendering index (CRI), energy efficiency, and lifespan. The "glass" from which the arc tube is made must withstand extremely high operating temperatures and is typically composed of translucent or transparent fused quartz or fused alumina.

What is the relationship between light intensity and photosynthetic rate?
The relationship between light intensity and photosynthetic rate is that if the intensity of the light is high then the rate of photosynthesis will increase. However the rate of photosynthesis will only increase to an extent after intensity of light reaches a certain point photosynthesis rate will stay still.
What is used to properly discharge voltage from an unplugged computer monitor?
high voltage probe
Does sprint increase height?
Yes it does. It is a high intensity exercise which will boost growth hormone drastically. This will make you taller.
What happens to light waves in a hot desert?
Light waves are always refracted to some degree by convection currents and vertical refractivity gradients in air. That's why astronomers want to see starlight that has passed through as little air as possible. It's also the reason that the legends of flying horses and magic carpets originated in the regions with the hottest deserts.
What is the motto of Huddard High School?
The motto of Huddard High School is 'Let your Light Shine'.
What are some of the most common uses of a HID light?
The are many uses for a high-intensity discharge lamp light for those that use one. The main use for the high-intensity discharge lamp lights is to cover a large area that needs light.
What does HID stand for in lighting?
High-intensity discharge
What kind of headlight does not have a filament?
high intensity discharge
What are some types of artificial light?
Incandescent, fluorescent LED, metal halide, halogen, HID (high intensity discharge), etc.
What is the HID Flashlight?
HID means High Intensity Discharge and is a modern form of lighting in which a compact arc is used as the source of light. They are more efficient that halide lamps.
Is high intensity light the same spectrum as white light?
The two things are quite unrelated. You have have high-intensity light that is white, or any color you want.
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 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.
How does light affect the pupil of the eye?
With high intensity light your pupil constricts. This happens to protect your retina from damage by light of high intensity.
Can lifting light weight with high intensity to failure stunt growth?
Lifting light weight with high intensity can stunt growth in children if used too early.
What types of lights does PIAA manufacture?
The PIAA manufactures several standard types of lights. The ones listed on their website are L.E.D. (Light Emitting Diodes), Halogen, and H.I.D. (High Intensity Discharge) lamps.
What do you call the flashing white light at parties and clubs?
The flashing white light that may occur at parties and/or clubs is called a "strobe light." A "strobe light" is a high-intensity flashing beam of light produced by charging a capacitor to a very high voltage then discharging it as a high-intensity flash of light in a tube
