As an alternative power source a 1.2v or 1.5v batterey is sometimes in the eyes of the power. Because a single led course at least requires 2.4v - 3.5v to be burning.
But now there is no need to wonder if one 1.2v batterey can turn on tens of led. Even a 220v AC lead, also energy-saving CFL lamps are also able to light up with Joule Thief Series.
