What does a fluorescent light tube usaually contain?
mercury vapour at low pressure.
Where will a full range of colors be better seen in a room with fluorescent or outside under daylight?
Daylight will have a more complete spectrum. An interesting experiment is to hold a CD close to a fluorescent lamp. The CD will act as a primitive diffraction grating, and you'll see distinct blobs of colour - not a continuous rainbow spectrum. You're seeing the light emitted by the various phosphors in the fluorescent tube.
What is the deference between incandescent and fluorescent lights?
An incandescent light uses electric current passing through a wire with a high resistance to current flow. That makes the wire very hot and it glows, producing the light. A fluorescent light uses electricity to charge a gas in a tube. The charged gas glows, producing the light. For the same amount of light, more electricity is needed in an incandescent light than in a fluorescent light, but developing and building fluorescent lights required more advanced technology than did incandescent lights.
What is the difference between daylight fluorescent and cool white fluorescent?
Daylight Fluorescent lamps have bluish-white illuminance, whereas coolwhite fluorescent lamps have yellowish-white illuminance.
Is gold fluorescent?
No.
How will you test starter and choke in fluorescent tube?
You can use a wire instead of the starter to test the tubes .. I did it, it works !
What would be the effect on the circuit should the starter be taken out the lamp is started?
Once started the fluorescent tube no longer needs the starter. In fact starters are designed to electrically "remove" themselves from the circuit when the fluorescent tube is conducting.

Is tube working if you remove stater?
Fluorescent tube with a separate starter? If it's working, you can remove the starter and it will keep going. But if you turn it off, it won't start next time you turn it on.
Can you use S10 in S2 starter?
An S2 starter is used when wiring 2 fluorescent tubes in series while S10 is used on a single tube
What is the working principal of a starter in a fluorescent lamp?
The electrodes at opposite ends of the fluorescent tube are also filament heaters. Upon starting, the two electrodes are connected in series through a closed switch within the starter, thus increasing the temperature of the heaters to initiate thermionic emission to ionise the gas in the tube. The starter then warms up and its contacts open, breaking the starting circuit, and the tube's electrode no longer act as heaters, but as discharge electrodes.
How do you get a starter out of a fluorescent light tube?
The starter should easily fit into the florescent fixture by sliding it into the hole and then securing it by twisting it in place. If you are having issues, you may need to check to ensure that you have the correct size starter for your florescent tube.
What are six main component of a fluorescent lamp tube light?

What is the use of starter in tube light?
Tube light requires two things to function . Very high starting voltage , and high voltage to continue the operation . The starter is a circuit which breaks at regular intervals . When you break a circuit and start again , high voltage spark takes place . This voltage is further amplified through the choke which is a transformer . Thus at the beginning the starter gives high voltage sparks . Due to this the current begins to flow through the tube and the tube begins to glow. Once the tube starts , the required voltage to sustain is quite low , which is provided by the choke .If the starter is bad the tube does not start . If the choke is bad or if the gas is low , the tube does not sustain its light .Fluorescent starters are used in several types of fluorescent lights. The starter is there to help the lamp light. When voltage is applied to the fluorescent lamp, here's what happens: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.Since the lighted fluorescent tube has a low resistance, the ballast now serves as a current limiter.When you turn on a fluorescent tube, the starter is a closed switch. The filaments at the ends of the tube are heated by electricity, and they create a cloud of electrons inside the tube. The fluorescent starter is a time-delay switch that opens after a second or two. When it opens, the voltage across the tube allows a stream of electrons to flow across the tube and ionize the mercury vapor.Without the starter, a steady stream of electrons is never created between the two filaments, and the lamp flickers. Without the ballast, the arc is a short circuit between the filaments, and this short circuit contains a lot of current. The current either vaporizes the filaments or causes the bulb to explode.
How does 4 tube fluorescent work?
A four tube fluorescent luminaire is just 4 separate fluorescent lamp circuits in one fitting. Look up 'how things work' etc to see a fluorescent lamp circuit.
What is the necessity of the starter in fluorescent lamp?
When line voltage is applied across the starter, it closes a circuit, connecting the filaments at the ends of the bulb in series so they heat up. Once the Mercury in the lamp is vaporized, the starter breaks the filament circuit, and the ballast provides a voltage pulse to start the current flow down the length of the tube, lighting it. While the bulb is lighted, the voltage across the starter is low and it does not energize the filaments. When you see a fluorescent lamp flashing, the bulb is worn out and the starter keeps vainly trying to start it. Eventually the starter will wear out and will need to be replaced also. Newer fluorescent fixtures have lamps and ballasts that do not require a starter.
