yes, special tube lights without starter are available which do not require a spark.
yes..if we replace magnetic ballast with electronic ballast...there is no need of starter if we use electronic ballast.
Starter is asmall device in a fluroscent tube light to start the ciruit. Once lit, starting circuit cuts off automatically
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
it will not glow
Bi Metallic
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.
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.
yes
No it will not. If you need increase the supply voltage and remove the choke.
Steel and copper
The starter is used to help the lamp light and acts like a closed switch. It allows electric current to flow through the filaments.
