how an we start up a fused tubelight again?

Answer 1

First of all, the "ballast" is not a transformer, but a shock coil and is used to create an extra current just in order to ionize the gas inside (a mixture of neon-if neon lamp, or others like krypton , argon and so on). That's why when you apply a shock to both sides of the tube (with the tube being tide in parallel withe the wires) and the filaments inside are burned or not you can start ionizing the gas. The ionized gas is current conducting so it by-passes the circuit from the wires, and also starts illuminating.

Answer 2

Fused tubelight will not start up. If a starter is burnt up, then there is a chance of starting a tubelight without the starter, like shorting the leads of the starter but a burnt up tube will not burn again. But why are you so particular about this. Are you so desperate that you cannot buy a new tube?

Answer 3

TUBELIGHTS CAN BE REPAIRED!

In a neighbourhood of me there is a group of people who repair the fused tubelights.

HOW?

When a tubelights goes fuse, everyone knows that the little iron wire that makes light; breaks so they give a ELECTRIC-SHOCK to the both sides of tube light, and with the heat of electric-shock the little iron wire MIGHT join again, the results are 60%

BUT DONT TRY THIS AT HOME!

Answer 4

logic say by replacing it, now every tube, lamp has type printed so, before you try to remove it, see those numbers just in case you break it, then you can get another one, some little lamps use a kind of fuse called starter and sometimes lamp is good and starter is broken, other times it can be broken the transformer called ballast, some lamps have two pins and you can get them out by turning them, others by pushing toward one of the sides, some others are screwed so, you might turn them like any light bulb. I was doing lighting in a big building for some years.
