WebJul 30, 2024 · Your fluorescent tube has filaments on both ends. Those filaments are heated by the starter current and then emit electrons into the gas filling of the tube. To assist that, they have a coating of lanthanides. Over time, those lanthanides amalgamate with the mercury gas filling and cannot serve their function any more. WebApr 1, 2000 · 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.
