High Pressure Sodium Vapour Lamp Ignitor

Typically these lights are used on sides of industrial buildings and in some street lamps.

High pressure sodium vapour lamp ignitor.

This evenings experimentation consists of attempting to start a high pressure sodium hps lamp with a microwave oven transformer at 2kv. High pressure sodium lamp hps lamp. Two varieties of such lamps exist. They are used for things such as security lighting.

This pulse starts an arc through the xenon gas. These types of lights are commonly found outside. Neither mercury vapor nor standard metal halide fixtures need ignitors to strike an arc through the lamp. There is an ignitor built into the ballast which sends a pulse of high voltage energy through the arc tube.

They emit bright yellow light. High pressure sodium lights are used for illuminating large outdoor areas. Sodium bulbs can last up to 20 000 hours. A high pressure sodium ballast is responsible for regulating the pressure in light fixtures that use high pressure sodium gas to produce the light.

Only high pressure sodium and pulse start metal halide fixtures have ignitors. The sodium is mixed with other impurities to create a. They are also commonly found in an indoor garden setting. The lamp turns sky blue as the xenon lights.

The heavy duty transformer or ballast is also long lived if the bulbs are changed out before they burn out. The sodium vapor strikes an arc over 240 c. 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.
