Mini Emergency Light by 9013 transistor

When you are born electricity problem switches off, should seek the system Emergency give the light. I begs for to advise Mini Emergency Light. By use electronics part, general seek easy and have no transformer. Then make this circuit has small-sized and economize very. From this circuit use power supply 3V then apply to lamp 2.4V 5W only. And friends can use Nicad Battery or , NiMH battery the size is 1.2V x 2 give the light has just enough. When the electricity switches off the system command give lamp stick bright get. The SW1 use for turn on or turn off this circuit. A friend may use this circuit help offer the convenience your please sir.
