Usually loud buzz sound could be emitted by inductive ballast, not the lamp itself, because of magnetowstriction vibration of inductor's iron core. Sometimes arc discharge becomes buzzy because of it's instability, at lamp end of life.

∙ 12y agoThe Transformer in the ballast gets old and dries out and begins to buzz.
When they are new they are very quiet but as they age they start to buzz.

Which light is brighter Metal Halide or mercury Vapor?
Between Metal Halide and Mercury Vapor the higher output is emitted from the Metal Halide lamp.
How do street lights produce light?
They produce light by using mercury vapor :D=======================Answer #2:Some (not many) pass electric current through mercury vapor, causing it to glow violet.Some pass electric current through sodium vapor, causing it to glow yellow.Some pass electric current through a thin wire, causing it to heat and glow ...a process is identical to that in every incandescent light bulb in your house.Some burn natural gas.
What are the symptoms of mercury vapor?
Mercury is a poisonous elements. Symptoms of poisoning by mercury vapor include insomnia, headaches, weakness, tremors, twitching, sensation disturbances and changes in nerve responses.
Does a metal halide and mercury vapor use the same ballast?
No. A mercury vapor lamp will work on a metal halide ballast, but not the other way around.
What are the phases of matter of mercury?
Solid, liquid, vapor and plasma
What element is in fluorescent light tubes?
mercury vapor
What element is found in fluorescent light bulbs?
Mercury Vapor
Which light is brighter Metal Halide or mercury Vapor?
Between Metal Halide and Mercury Vapor the higher output is emitted from the Metal Halide lamp.
How the tube light works?
It is a low weight mercury-vapor gas-release light that uses fluorescence to deliver obvious light. An electric current in the gas energizes mercury vapor which creates short-wave bright light that then causes a phosphor covering within the globule to sparkle.
Why Mercury vapours are used in Mercury vapor lamp?
Ionized mercury vapor radiates in the near ultra-violet (a high energy source of radiation) which energizes the fluorescent coating inside the bulbs.
Green light emitted by excited mercury vapor corresponds to a particular energy transition in the mercury atom a more energetic transition might emit?
Blue Light
How do you fix Mercury Vapor light?
Dude! Did you not read your question??? You said Mercury Vapor! You don't fix it! It's Mercury vapor. You're "playing with fire there." You need to call your local municipality/township and find out where the nearest hazardous disposal facility is for this bulb and dispose of it properly. Then go to the store and buy a new bulb.
When alchohol and mercury boil they both change from a liquid to what?
They change from a liquid to a vapor (gas).
How does electron allow a fluroscent tube to glow?
The electrons in the mercury arc current in the tube causes the mercury vapor to emit ultraviolet light. The inside surface of the tube is coated with a phosphor that glows with visible light when hit by ultraviolet light.
Do moths attract to a certain light?
I know that Black lights and mercury vapor lights (including CFLs) attract more moths than incandescent lamps, but I'm not sure if black lights are better than mercury vapor lights.
How many lumens are in a 400 watt mercury vapor light bulb?
A 400 watt Mercury vapor light bulb produces roughly 23,000 lumens. In comparison to a 400 watt metal haloid and or high-pressure sodium, not as good. Metal haliod and high-pressure sodium produces 30,000 lumens.
The light-producing element in a fluorescent bulb is the?
Light in fluorescent bulbs occurs when electricity excites the mercury vapor inside the tubular glass bulb.
