High Pressure Mercury Lamp Ballast

Metal halides high pressure sodium mercury vapor.

High pressure mercury lamp ballast.

A very first appearance at a circuit diagram could be confusing however if you could review a subway map you can check out schematics. 2 pin lamp ballasts magnetic 4 pin lamp ballasts electronic 4 pin 2d butterfly plug in ballasts. Fluorescent full spectrum light bulbs. Mercury lamps are still a legitimate and widely used hid lamp source.

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. Most magnetic hid ballasts are multi tap meaning they can be connected to several different voltages. Large installed base of mercury lamps. Here we display wiring diagrams for metal halide probe start mercury vapor ballast and high pressure sodium hid ballast kits.

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. Hid flood lights exports to eu middle east russia. Only high pressure sodium and pulse start metal halide fixtures have ignitors. Two varieties of such lamps exist.

After that the lamp would heat fast and mercury became a vapor. 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. Metal halide bulbs ballasts. Mainly products 400 watt metal halide ballast for 400w metal halide.

Lamps of today are high pressure lamps with a fused quartz inner discharge tube. Medium base metal halide. Neither mercury vapor nor standard metal halide fixtures need ignitors to strike an arc through the lamp. 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.

As the main arc strikes and the gas heats up and increases in pressure the light shifts into the visible range and the high gas pressure causes. Ballast wiring diagrams for hid ballast kits including metal halide and high pressure sodium lighting ballasts. Standard medium base metal halide. The light would intensify as the arc grew stronger in the tube.
