What Is A High Pressure Sodium Bulb

The heat generated by the arc then vaporizes the mercury and sodium.

What is a high pressure sodium bulb.

The mercury vapor raises the gas pressure and operating. The lamp is an improvement over the lps lamp in that it has more acceptable color with the great efficiency of the sodium lamp. The most common problem with a high pressure sodium light is the bulb. These bulbs cannot be interchanged without changing their ballast the regulating element in all light bulbs.

If the tube is black the bulb is definitely burned out. The first course of action is to simply change the bulb. In a high pressure sodium lamp a compact arc tube contains a mixture of xenon sodium and mercury. Most high pressure sodium light systems normally last between 12 000 to 24 000 hours.

The xenon gas which is easily ionized facilitates striking the arc when voltage is applied across the electrodes. Two varieties of such lamps exist. The primary visual difference between them is that metal halide light is white and the light emitted from a high pressure sodium bulb is amber orange.

We also offer special conversion metal halide bulbs that can be used with fixtures intended for high pressure sodium light bulbs. Viavolt 600 watt high pressure sodium replacement hid light bulb model v600hps 42 28 42 28. A metal halide bulb produces about 65 110 lumens of light per watt while a high pressure sodium bulb produces about 96 150 lumens of light per watt. A high pressure sodium bulb produces light that is reddish yellow while metal halide bulbs produce a much more balanced white light that has more of the visual spectrum.

Hps fixtures are an improvement over low pressure sodium lps bulbs because of a better color rendering. The better color rendering comes with a bit of sacrifice it has less efficiency than the lps. Observe the interior gas tube for any signs of discoloration. High pressure sodium lamp hps lamp the hps lamp is the most ubiquitous lamp for street lighting on the planet.

When deciding high pressure sodium vs led it s first best to describe each one in depth since both produce light in different ways. A 400w bulb can easily cover a gardening area of approximately 15 square feet while a 1000w bulb can be used on a growing area of around 7x7 feet. 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. What is a high pressure sodium hps light.

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. Check the porcelain holder for any signs of deep cracks or breaks.
