1.5v High Power Joule Thief without using any toroid,resistor & capacitor

This is a unique joule thief circuit which i accidentally discovered while experimenting with various components.
The only components used is 2N2222A,BC557B and 2 inductor as shown in circuit diagram in order to power 2 x10mm Leds connected in parallel configuration.
The best part no winding of any toroid.The current consumption less than 50mA for 1.38volts battery.
This video was filmed using Sony Alpha Nex-5n ,18mm, F3.5
