The Problem is this whole circuit suck out nearly 250mA.

So its depend on ur Battery capacity.

My Battery is 2500mA.

So max time is more than 8 Hours at max BRIGHT

oops!! great macho;but the prob is 250mA;usually a just LED draws abt 20mA neda?

yeah macho but battery is inexpensive ne;so if we use 2 we can use it for very longtime;but ur circuit is great;sometime we need to boost 12v to abt 14.4v like that ne;

me 100uH coil eka hada ganna widiyak nadda?mata ekak hoya ganna ne

I use 2500mA Rechargable cells. so need to worry.

Machan uba gawa old PC Power Supply Units thiyanawada. ewage thiyana inductors nearly 100uH. ( look 5V Regulation side )
