Schematics and description of a very efficient "Joule thief" circuit. It can light up an LED 10 Watt 220 Volt lamp with a 1.2 Volt rechargeable battery. It is capable of staying lit for about 20 minutes. At the beginning the it is very bright, then dims out little by little.

Fascinating circuit. Thanks for sharing.
I am working on other highly efficient energy devices, hope to get consistent results soon.
