How do you troubleshoot a high pressure sodium light?
The most common problem with a high pressure sodium light is the bulb. The first course of action is to simply change the bulb. Observe the interior gas tube for any signs of discoloration. If the tube is black, the bulb is definitely burned out.
Why does my sodium light go on and off?
A high pressure sodium lamp cycling on and off usually indicates the lamp has reached the end of its normal life.
Do sodium lights have a ballast?
The tube of a high pressure sodium light is generally made out of aluminium oxide, due to its resistance to the high pressure, and xenon, that is used as a starter for the light because it won’t react with the other gases. Voltage runs to the light through a ballast, which regulates the current.
How can you tell if a ballast is bad?
If your fluorescent lighting is displaying any of the signs below, it could be a symptom of a bad ballast:
- Flickering.
- Buzzing.
- Delayed start.
- Low output.
- Inconsistent lighting levels.
- Switch to an electronic ballast, keep lamp.
- Switch to an electronic ballast, switch to a T8 fluorescent.
Do HPS bulbs wear out?
HPS bulbs enhanced with the blue spectrum will usually degrade in the blue spectrum output first, due to the specific compounds used. Blue spectrum aside, HPS lights degrade a bit slower than MH lights. If you use HPS bulbs, plan to replace them after 10-14 months of use.
Can you replace a high pressure 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.
How long do high pressure sodium bulbs last?
High Pressure Sodium lights maintain their luminescence fairly well with 90% still available halfway through their lifespan (around 12,000 hours). HPS bulbs typically emit 80% of their original rated output at the end of life (around 24,000 hours).
Do high pressure sodium bulbs need a ballast?
HPS lamps require ballasts to regulate the arc current flow and deliver the proper voltage to the arc. HPS lamps do not contain starting electrodes. Instead, an electronic starting circuit within the ballast generates a high-voltage pulse to the operating electrodes.
Which ballast is used in sodium lamp?

How long do sodium bulbs last?
What is the most common problem with high pressure sodium lights?
The heavy duty transformer or ballast is also long lived if the bulbs are changed out before they burn out. These lights are typically controlled by a photocell that turns the light on at dusk. The most common problem with a high pressure sodium light is the bulb.
What are the disadvantages of sodium vapor lights?
Amongst the minor deficiencies in sodium vapor lighting are the following: High Pressure Sodium lights contain a small amount of toxic mercury. The mercury inside the bulbs is a hazardous materials that can present a waste disposal issue at the end of light’s life.
What are the minor deficiencies in sodium vapor lighting?
What are the Minor Deficiencies in Low (LPS) and High Pressure (HPS) Sodium Lights: Amongst the minor deficiencies in sodium vapor lighting are the following: High Pressure Sodium lights contain a small amount of toxic mercury. The mercury inside the bulbs is a hazardous materials that can present a waste disposal issue at the end of light’s life.
What to do if your high pressure sodium light is not working?
These lights are typically controlled by a photocell that turns the light on at dusk. The most common problem with a high pressure sodium light is the bulb. The first course of action is to simply change the bulb. Observe the interior gas tube for any signs of discoloration.
