To prolong the life of halogen lamps, you need a soft start device. In this video, I'll show you how it works

Excellent Demonstration - Well Done !
thank you
Thank You ! As made similar soft start for oscillograph tube ? ~6,3 V
What relay and NTC thermistor should I use for soft start 230V AC incandescent bulb (150W)?
Tek potansiometreni led e baglayip direnci azalta artira bilirmiyiz Soyle dusun ledin arti bacagina 500R dirnc baglayip 12voltu 8volt civarini indiriyorum cok parlak olmasin onun yerine potansiometre nasil baglanir bacaklar olarak😊
Does this also allows the thermistor to start cooling so it is ready sooner? Or is it keeping the relay activated?

it will keep the relay activated

I think it's both. By keeping relay activated, switch will be constantly closed over NTC thermistor keeping it short circuited. So all current will bypass the thermistor and travel through the short. And the voltage across the thermistor is going to be zero. So the thermistor should start cooling. I suppose so, I'm not much of an electrician...
