What Is A High Pressure Sodium Bulb

In a high pressure sodium lamp a compact arc tube contains a mixture of xenon sodium and mercury.

What is a high pressure sodium bulb.

If the tube is black the bulb is definitely burned out. Hps bulbs use sodium particles and gases to produce light. The most common problem with a high pressure sodium light is the bulb. Most high pressure sodium light systems normally last between 12 000 to 24 000 hours.

Hps fixtures are an improvement over low pressure sodium lps bulbs because of a better color rendering. The mercury vapor raises the gas pressure and operating. Observe the interior gas tube for any signs of discoloration. Viavolt 600 watt high pressure sodium replacement hid light bulb model v600hps 42 28 42 28.

Two varieties of such lamps exist. Check the porcelain holder for any signs of deep cracks or breaks. The better color rendering comes with a bit of sacrifice it has less efficiency than the lps. High pressure sodium lamp hps lamp the hps lamp is the most ubiquitous lamp for street lighting on the planet.

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. Sunlite 100 watt ed17 high pressure sodium hid bulb 2100k e26 base 8500 lumens metal halide light bulb 2 pack model hd02487 2 19 99 19 99. What is a high pressure sodium hps light. 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.

These bulbs cannot be interchanged without changing their ballast the regulating element in all light bulbs. The heat generated by the arc then vaporizes the mercury and sodium. The lamp is an improvement over the lps lamp in that it has more acceptable color with the great efficiency of the sodium lamp. 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.

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. The first course of action is to simply change the bulb. Their operation is a bit different and they therefore require different ballasts. Set your store to see local availability add to cart.

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. The xenon gas which is easily ionized facilitates striking the arc when voltage is applied across the electrodes.
