Do mercury vapor bulbs need ballast?

Do mercury vapor bulbs need ballast?

As with fluorescent lights, mercury vapor lamps require a ballast to supply the proper voltage and regulate the current to the electrodes. The ballast is designed to be used with a specific size, or wattage, of bulb.

How does a mercury Vapour lamp work?

A mercury-vapor lamp is a gas-discharge lamp that uses an electric arc through vaporized mercury to produce light. They operate at an internal pressure of around one atmosphere and require special fixtures, as well as an electrical ballast.

Is ignitor is required for starting mercury Vapour lamp?

The mercury vapor and neon gas (pink in color) present in the bulb requires high voltage at the starting to illuminate light. Hence by connecting the ballast and ignitor to this lamp, the mercury vapor and neon gas get heated up and expands the bulb inside to illuminate the light.

Why do mercury vapor lights turn 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.

How do I know if my mercury vapor bulb is bad?

Replace the light bulb if it flickers, dims or changes colors drastically. Be sure to install the light according to the manufacturer’s instructions. The light will not work if the pins are not seated properly. If the light is tinted pink or blue after installing a new bulb, replace the capacitor.

Can you use a metal halide ballast on mercury vapor?

They do not manufacture “mercury vapor” ballasts anymore, so you would use a metal halide ballast and MH or MV lamp. On occasion, pairing a 175 MV lamp with a 150W MH ballast, will work, but will cause the ballast to overclock, and will greatly shorten the life of that ballast and/or lamp.

How do you test a mercury vapor bulb?

  1. Make sure the light fixture is plugged in and the circuit breaker switch is on.
  2. Replace the light bulb if it flickers, dims or changes colors drastically.
  3. Check the compatibility of your mercury vapor bulb and its ballast if the light shuts off before it is fully warmed up.
  4. Inspect the condition of the ballast.

Can you replace a mercury vapor 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.

Can you put a LED bulb in a mercury vapor fixture?

Retrofit is a direct replacement of the conventional halogen or high pressure sodium bulbs with LED lamps. After the replacement of 175W mercury vapor lamps with LED, you can enjoy 80,000 hours life span and flicker free illumination.

How do you troubleshoot a mercury vapor light?

What is the difference between sodium and mercury Vapour lamps?

Answer: The light in Sodium Vapour lamp is from an atomic emission process whereas in Mercury Vapour Lamp it is, finally, from fluorescence emission. The mechanism of light emission in a sodium vapour lamp is simple and straight-forward.

Where do you use mercury vapor light bulbs?

Mercury vapor lamps are bright, long-lasting light sources that are often used to light large areas such as streets, gyms, sports arenas, banks, or stores. The bulbs have an inner quartz tube containing the mercury vapor discharge.

How does a self ballasted mercury vapor lamp work?

Self-ballasted (SB) lamps are mercury vapor lamps with a filament inside connected in series with the arc tube that functions as an electrical ballast. This is the only kind of mercury vapor lamp that can be connected directly to the mains without an external ballast.

When was the first mercury vapor lamp made?

1892 – Developed an experimental mercury vapor lamp Leo Arons, (University of Berlin). His lamp worked fine but had a green blue color that was not acceptable to most people. 1901 – The First Commercial Mercury Vapor Lamp

How does a starter work on a light bulb?

The starter (which is simply a timed switch) allows current to flow through the filaments at the ends of the tube. The current causes the starter’s contacts to heat up and open, thus interrupting the flow of current. The tube lights.
