How do I know if my HPS bulb is bad?
When the bulb produces no light, you know it is bad. The less sarcastic answer is to look at the small tube inside the bulb. If the tube has a dark or even a black color to it, that means it is dead and will not work.
How do you test an HPS 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. Check the porcelain holder for any signs of deep cracks or breaks.
Why is my HPS light not working?
If the MH lamp starts and a new HPS lamp does not start, the ignitor probably needs to be replaced. If a new bulb, ignitor, and/or capacitor do not make the fixture work, then the ballast is probably defective.
Why does my high pressure 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.
Can you replace a high pressure sodium bulb with LED?
High pressure sodium bulbs (“lamps”) are an old standby for lighting that’s still used today in spite of so much talk of LED lights. LEDs, however, are better able to control their light, which is why a lower-watt LED can replace a higher-watt high pressure sodium bulb.
What was a major problem in producing a high pressure sodium lamp?
Although the sodium light requires less energy that other types of light and is more efficient, there are drawbacks to the use of these light sources. Metallic sodium reacts with the moisture in the air and can explode if the bulb is broken.
How do I know if my sodium light bulb is bad?
The Bulb. 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.
How to troubleshoot high pressure sodium lights?
Troubleshooting High Pressure Sodium Lights 1 The Bulb. The most common problem with a high pressure sodium light is the bulb. 2 Wiring. Check all wiring for any signs of loose connections or burned wires. 3 Ballast and Capacitor. Test the input voltage and output voltage of the ballast transformer.
How do you test a high pressure sodium ballast?
Here is a quick guide on how to test your high-pressure sodium ballast to make sure it is properly and efficiently igniting the bulb. Remove the lamp. Make sure you turn off all power first to safely remove the lamp from the location. Visually inspect the lamp for proper connections and contacts.
How long do high pressure sodium light bulbs last?
Troubleshooting High Pressure Sodium Lights. They emit bright yellow light. Typically these lights are used on sides of industrial buildings and in some street lamps. Sodium bulbs can last up to 20,000 hours. The heavy duty transformer or ballast is also long lived if the bulbs are changed out before they burn out.
