Ballast For High Pressure Sodium Vapour Lamps

They are used for things such as security lighting.

Ballast for high pressure sodium vapour lamps.

We even have 4 tap and 5 tap ballasts for maximum flexibility. So there is no enough space to provide any starting electrode in the arc tube. A ballast with igniter is used for this purpose. Whether you re lighting a parking lot or a construction site our hps ballasts will keep your lamps lit so you can be confident your outdoor areas are safe.

In a high pressure sodium lamp a compact arc tube contains a mixture of xenon sodium and mercury. The mercury vapor raises the gas pressure and operating voltage and. Two varieties of such lamps exist. High pressure sodium ballast wiring diagram sodium vapor lamp circuit diagram unique low pressure sodium vapour lamp perfect lamp efficacy efficiency.

Typically these lights are used on sides of industrial buildings and in some street lamps. The heat generated by the arc then vaporizes the mercury and sodium. We have the high pressure sodium lamp ballasts you need for effectively lighting your outdoor application. They emit bright yellow light.

These types of lights are commonly found outside. High pressure sodium lights are used for illuminating large outdoor areas. 4 and 5 tap hps light ballasts for maximum versatility.

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. 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 mercury vapor lamp would behave on a high pressure sodium ballast so i screwed it in the socket the lamp started up red and warmed up to a cool white color as expected howeven a minute after reaching full brightness the arc extinguishes i ve observed this closely and the lamp cycles on the 70 watt hps ballast why is this so. A high pressure sodium ballast is responsible for regulating the pressure in light fixtures that use high pressure sodium gas to produce the light.

We also offer special conversion metal halide bulbs that can be used with fixtures intended for high pressure sodium light bulbs. The xenon gas which is easily ionized facilitates striking the arc when voltage is applied across the electrodes. The heavy duty transformer or ballast is also long lived if the bulbs are changed out before they burn out. So a higher voltage is required to initiate the arc.
