What is low pressure sodium lighting?
What is a Low Pressure Sodium Light? Low pressure sodium vapor (LPS) lights are a specific type of gas-discharge light (also known as a high intensity discharge, HID or arc light). The bulb principally contains solid sodium metal inside a borosilicate glass tube that vaporizes once the lamp is turned on.
What are low pressure sodium lights used for?
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….ANSI HPS ballast codes.
| Power output | ANSI codes |

| 1000 W | S52 |
What is the difference between high pressure and low pressure sodium lamps?
Low-pressure sodium lights produce the greatest amount of light per watt of energy consumed. High-pressure lights are slightly less efficient. The efficacy in lumens per watt for low-pressure sodium lights is 60 to 150; for high-pressure lights it is 50 to 140.
Why is HPS better than LED?
The heat per watt is far greater with an HPS fixture compared to LED. This technology is far more efficient in transferring energy in to light, as it produces less heat and has a higher wattage equivalency to HPS (600w vs 1000w).
Can you replace sodium bulb with LED?
LED corn cob lights are one of the most efficient ways to replace metal halide, mercury vapor, and high-pressure sodium HID bulbs.
Why does my sodium light go on and off?
When it nears end of life, as in the case of your lamp, reactions with the lamp’s alumina (synthetic sapphire, really) shell have depleted much of the sodium from the lamp, raising the voltage required to maintain the discharge to a point where when the lamp is fully hot, the ballast can no longer provide that voltage.
Should I use HPS or LED?
LEDs are far more efficient than HID lighting. Pound-for-pound — or rather kilowatt-for-kilowatt — they produce more light than HPS fixtures. The diodes of an LED fixture are inherently superior at converting electricity into light. Along with better electrical efficiency comes better efficacy.
How many lumens is a 70 watt high pressure sodium bulb?
6300
70-watt HPS bulbs provide between 6300 and 7000 lumens of light in frosted and clear options.
How does the high pressure sodium lamps work?
High pressure sodium lamps are a type of gas-discharge lamp. This means they create light by sending electricity between electrodes in a bulb which is filled with a noble gas. The noble gas serves a few purposes. Due to its low thermal conductivity, it helps the lamp to start while minimizing loss of energy through heat.
What is a low pressure sodium lamp?
Low-pressure sodium (LPS) lamps have a borosilicate glass gas discharge tube (arc tube) containing solid sodium, a small amount of neon, and argon gas in a Penning mixture to start the gas discharge. The discharge tube may be linear (SLI lamp) or U-shaped. When the lamp is first started,…
How to dispose of high-pressure sodium light bulbs?
How to Dispose of High-Pressure Sodium Light Bulbs. Place the bulb in a padded container where it cannot break. The ideal container would be whatever specially designed box the bulb originally came in, or the one which contains the replacement bulb. If you don’t have such a box, use a cardboard box or other rigid container.
What are high pressure sodium lamps?
High Pressure Sodium Lamps or HPS Lamps. High-pressure sodium lamps (also known as HPS Lamps or HPS lights) are a type of sodium lamp that is widely used in industrial lighting and many public outdoor areas.
