High Pressure Mercury Lamp Ballast

Standard medium base metal halide.

High pressure mercury lamp ballast.

A sodium vapor lamp is a gas discharge lamp that uses sodium in an excited state to produce light at a characteristic wavelength near 589 nm. The light would intensify as the arc grew stronger in the tube. Metal halides high pressure sodium mercury vapor. A very first appearance at a circuit diagram could be confusing however if you could review a subway map you can check out schematics.

Fluorescent full spectrum light bulbs. Mainly products 400 watt metal halide ballast for 400w metal halide. Medium base metal halide. Low pressure and high pressure low pressure sodium lamps are highly efficient electrical light sources but their yellow light restricts applications to outdoor lighting such as street lamps where they are widely used.

Here we display wiring diagrams for metal halide probe start mercury vapor ballast and high pressure sodium hid ballast kits. Metal halide bulbs ballasts. Mercury lamps are still a legitimate and widely used hid lamp source. Only high pressure sodium and pulse start metal halide fixtures have ignitors.

An ignitor is used when high pressure is necessary to strike an arc through certain materials and get the temperature up very quickly inside it. Most magnetic hid ballasts are multi tap meaning they can be connected to several different voltages. Lamps of today are high pressure lamps with a fused quartz inner discharge tube. 2 pin lamp ballasts magnetic 4 pin lamp ballasts electronic 4 pin 2d butterfly plug in ballasts.

Hid lamps require metal halide ballasts or high pressure sodium ballasts for metal halide flood lights hps flood lights magnetic ballasts kits include high pressure sodium ballasts or metal halide ballasts ignitor starter capacitor and hid bulbs. Mercury vapor lamps have found the greatest use in industrial applications and outdoor lighting because of their low cost and long life and lamp sizes of up to 1 000 watts. After that the lamp would heat fast and mercury became a vapor. Hid flood lights exports to eu middle east russia.

Large installed base of mercury lamps. Ballast wiring diagrams for hid ballast kits including metal halide and high pressure sodium lighting ballasts. When a mercury vapor lamp is first turned on it will produce a dark blue glow because only a small amount of the mercury is ionized and the gas pressure in the arc tube is very low so much of the light is produced in the ultraviolet mercury bands. Neither mercury vapor nor standard metal halide fixtures need ignitors to strike an arc through the lamp.
