What is electronic blast for a CFL lamp?
The electronic BALLAST is a circuit that limits the current through the fluorescent bulb to the design value. It also provides a pulse of high voltage to start the bulb conducting when it is switched on.
What form of helium is filled in helium cylinders?
Gas under high pressure
What is the main difference between an incandescent light bulb and compact fluorscent light bulb?
An incandescent bulb differs from a fluorescent based on how it produces light. "Incandescent" means producing light through heat, this is essentially how an incandescent bulb lights. As current travels to the tungsten filament, the filament heats and lights up as the tungsten filament begins to deteriorate and eventually fail. Fluorescent bulbs produce light when current excites gasses inside the glass envelope. As the gasses get excited they emit photons. Interestingly, the light produced by a fluorescent bulb does not fall along the visible spectrum until it passes through the white, phosphor coating on the inside of the bulb. And there you have it.
How is a fluorescent light made?
A fluorescent bulb uses a completely different method to produce light. There are electrodes at both ends of a fluorescent tube, and a gas containing argon and mercury vapor is inside the tube. A stream of electrons flows through the gas from one electrode to the other (in a manner similar to the stream of electrons in a cathode ray tube). These electrons bump into the mercury atoms and excite them. As the mercury atoms move from the excited state back to the unexcited state, they give off ultraviolet photons. These photons hit the phosphor coating the inside of the fluorescent tube, and this phosphor creates visible light. It sounds complicated, so lets go through it again in slow motion:There is a stream of electrons flowing between the electrodes at both ends of the fluorescent bulb.The electrons interact with mercury vapor atoms floating inside the bulb.The mercury atoms become excited, and when they return to an unexcited state they release photons of light in the ultraviolet region of the spectrum.These ultraviolet photons collide with the phosphor coating the inside of the bulb, and the phosphor creates visible light.The phosphor fluoresces to produce light.A fluorescent bulb produces less heat, so it is much more efficient. A fluorescent bulb can produce between 50 and 100 lumens per watt. This makes fluorescent bulbs four to six times more efficient than incandescent bulbs. That's why you can buy a 15-watt fluorescent bulb that produces the same amount of light as a 60-watt incandescent bulb.
What are some examples of bulbs?
Different types of bulbs are:1. Incandescent bulb2. Halogen bulb3. Fluorescent tube bulb4. Compact fluorescent bulb5. High intensity discharge lamp or mercury bulb6. Low-pressure sodium lamp or metal halide bulb7. LED or light emitting diodes bulb
Is a fluorescent bulb is filled with gas at a high pressure?
No, just an inert gas and mercury vapor at close to atmospheric pressure. Without the inert gas it would be near vacuum, as very little mercury is needed.
What are the different types of light?
Incandescent Lamps Light Emitting Diode Neon Lamps Fluorescent Tubes Compact Fluorescent Lamps Halogen Lamps Metal Halide Lamps High Intensity Discharge Lamps Low Pressure Sodium Lamps High Pressure Sodium Lamps
Can you use a 70 watt high pressure sodium bulb in a 150 watt ballast?
No, you can not use a 150 watt high pressure sodium bulb with a 70 watt ballast.
Does a 400W high pressure sodium bulb have silver in it?
The 400W high pressure Sodium bulb contains a silver lining inside the frame to give better reflection of light. However, no silver is found inside the bulb.
What is electronic blast for a CFL lamp?

What form of helium is filled in helium cylinders?
Gas under high pressure
Do you need a ballast for every type of HID bulb?
All high-intensity discharge (HID) bulbs, and all fluorescent bulbs, require a ballast, which is a device that limits current. It can raise the voltage and/or heat the bulb cathodes.
Which property is not important when selecting a material to use as a light bulb?
High vapor pressure
Which high intensity disharge bulb do you use to grow weed?
The bulb should be in the red end of the light spectrum. One HID lamp is the high pressure sodium lamp.
What is CFL mhl and hpmv lamps?
The abbreviations are CFL - Compact Fluorescent Lamp, MHL - Metal Halide Lamp, HPMV - High Pressure Mercury Vapor, and one more is HPS - High Pressure Sodium lamp
Is pharmacy technician a high pressure job?
Yes. You have to be sure that the prescription is filled EXACTLY.
Why do you use starter for an incandescent lamp?
The starter will send a delayed high voltage electricity to the gas within the fluorescent bulb that cause the gas to be ionized and conduct electricity.
