heated 2sc1096 in Joule ringer

[dave_j_fan]

Hi guys ,
 I am making  Joule ringer 2.0 . Want to do in EI core . to light 5w LED lamp
 there are videos by LIDMOTOR
 showing low amp draw  like 140mA

 but here it is heating the transistor ..amp is >700mA
 
 there are 2 changes from main design
1)operating for 220V
2)transistor is 2sc1096

expert comments needed

There's no good reason to use such a design in 2017. Use a proper PWM controller.

And going all the way to 220Vac is probably the most inefficient way of powering LEDs.
Why not drive the LED directly using a proper constant current boost converter?
