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.
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 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.
Does a Philips 150cm 58 watt tube light need a starter?
yes
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 !
Why does the starter not strike after it has established the glow in the tube?
The starter does not strike after establishing the glow in the tube because it is designed to operate only during the initial phase of starting the fluorescent lamp. Once the gas in the tube ionizes and allows current to flow, the starter automatically disconnects from the circuit. This prevents it from interfering with the normal operation of the lamp, allowing the ballast to regulate the current and maintain the light output.
How does a choke work in a tube light circuit?
The choke works in conjunction with a starter . When you turn on the light , voltage is applied to the choke, and when the switch opens after a few seconds, it creates a high voltage across the contacts at each end of the tube. This starts the ionization of the gas , which glows. Once ionized, it continues producing light even when the voltage applied is only 120 VAC, the power line voltage.
Does a tube light glow without starter?
yes..if we replace magnetic ballast with electronic ballast...there is no need of starter if we use electronic ballast.
What is starter in tube light?
Starter is asmall device in a fluroscent tube light to start the ciruit. Once lit, starting circuit cuts off automatically
How tube light start by using starter?
A starter initially provides a path to complete the circuit. The tube light starts when the current flows through the ionized gas in the main tube. woodenboatusa.com
Can tube light golw without starter?
yes, special tube lights without starter are available which do not require a spark.
Does the tube light glow with out starter and choke?
it will not glow
Which material are used in tube light starter?
Bi Metallic
Where is the position of capacitance of tube light?
The small cylindrical thing that You see (generally on a side of the choke coil) is the "starter " of the tube light. This is the capacitor used in tube light. And is used to provide a momentary voltage rise of nearly 400V to start up the tube light hence Starter.
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.
Does a Philips 150cm 58 watt tube light need a starter?
yes
Why is my tube light flickering intermittently?
Your tube light may be flickering intermittently due to a loose connection, a faulty starter, or a problem with the ballast. It is recommended to check and tighten the connections, replace the starter, or have a professional inspect and repair the ballast if needed.
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 !
Why starter used in tube light fitting?
The starter is used to help the lamp light and acts like a closed switch. It allows electric current to flow through the filaments.
