You can use a wire instead of the starter to test the tubes .. I did it, it works !

How choke coil limit current to the fluorescent tube?

A choke coil, also known as a ballast, limits the current to a fluorescent tube by providing a high impedance to the flow of current. This high impedance restricts the current flowing through the tube, allowing it to operate within its required current range. The choke coil also helps regulate the starting voltage and stabilize the operation of the tube.


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.


Is tube light run without choke?

No it will not. If you need increase the supply voltage and remove the choke.


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.


How does fluorescent tube glow?

A fluorescent lamp is a glass tube containing some mercury vapor, with a phosphorescent coating on the interior surface of the tube.The mercury vapor is made to glow by using a high voltage across its electrodes that sets off an electric arc discharge in the tube. The discharge can also be described as a conducting plasma.The resulting flow of current through the mercury vapor is stable and well-controlled by an external ballast, or loading device, which consists of a high-inductance choke-coil that is connected in series with the tube.The continuing dischange glow is invisible to the human eye but it causes the phosphorescent coating on the interior surface of the tube to emit visible light.A fluorescent tube lamp works by using the fluorescence principle. It contains two filaments, one at each end of the tube, which glow to heat up the gas contained inside the tube.The inner surface of the tube is coated with compound of elements having fluorescent properties, such as phosphorus. When it was manufactured all normal air was removed from the tube. In place of the air just a small trace of a gas is put into the tube, such as mercury vapor (for a white color), carbon dioxide (for green), neon (for red color), etc.When the electrical supply is turned on, what happens is that the two filaments glow and then the contacts of the starter open. This action provides a voltage across the tube that is high enough to ionise the warmed-up gas inside the tube. This ionised gas, also called a "plasma", excites the special fluorescent coating on the inside of the tube so that it gives out visible light.Note about the need for a choke and a starterWithout a high inductance choke in series with the tube, the plasma in the tube would simply short-out the service wires. That would always cause the circuit's protective fuse to blow - or its circuit breaker to trip - to cut off the supply of current to the tube. If that happened the tube light would never be able to perform its intended purpose, which is to continue running - and giving out a continuous light - for long periods of time.The starter is a special kind of switch: its contacts are made of a metal alloy which, soon after a voltage is applied, heats up and bends, causing the switch contacts to open.So a high-inductance choke must be used in circuit with the starter and the tube for two reasons:firstly the choke generates a high voltage pulse across the tube when the starter's contacts open. That pulse causes the gas in the tube to ionise and become a low-resistance plasma andsecondly, because it is wired in series with the tube, the choke greatly reduces the current drawn by the tube once it contains the low-resistance plasma.For more information see the Related link below and the answers to the Related Questions.

Does the tube light glow with out starter and choke?

it will not glow


What is the function of choke in tube lights?

To limit the current flowing through the fluorescent tube once its gas has ionised.


What is principle of fluorescent tube light how choke gives transient voltage across tube at the time of starting?

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.

What is the use of choke in the fluorescent tube?

The inductance primarily serves to limit current flow to the correct level for the tube. It also can be used during startup to provide an inductive 'kick' forming a higher-voltage pulse to start the lamp.


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.
