Why does my mercury vapor light go on and off?
If the eye sees light reflected from the pole or a nearby building it will turn the light off, then back on, all night. If the eye sees too much sun set it will be slow to turn on, same thing if it sees too much sunrise it will be quick to turn off.
Can you put an LED bulb in a mercury vapor fixture?
Corn Cob LED lights are a truly great invention. You can’t eat them, but you can light them! They are a wonderful replacement for the technologies of the past, such as metal halide and mercury vapor.
Can you replace a mercury vapor bulb with a metal halide bulb?
Due to their low lighting efficiency, mercury vapor lamps should be replaced wherever possible. In areas where identifying colors is important, they should be replaced with metal halide fixtures; if color is not important, they should be replaced with high-pressure sodium fixtures.
Can I use a metal halide bulb in a mercury vapor fixture?
Incandescent and mercury vapor lamps in exterior locations should be replaced with metal halide, high-pressure sodium and/or low-pressure sodium lamps. If color is important, metal halide lamps are a good option.
What is a main disadvantage of mercury Vapour lamps?
The main drawbacks of high-pressure mercury vapour lamps are their slow 4-7 minute warm-up time, middling energy efficiency (about 50 lumens per watt), and inferior colour rendering compared to metal halide lamps.
How can you tell if a high pressure sodium bulb is bad?
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 do you test a sodium vapor lamp?
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.
- Step 1 – Remove the Lamp.
- Step 2 – Visually Inspect the Lamp.
- Step 3 – Check Accessories.
- Step 4 – Test the Voltage.
- Step 5 – Check the Ballast.
- Step 6 – Check the Short-circuit Current.
