Make energy saving lamp for home use using 2 x AA or 2 x AAA batteries

Highly efficient energy saving lamp power up by 2 x AA or 2 x AAA batteries voltage within 3 volt down to 0.8 volt. I am going to stick this on my wall :) the battery should last for a long time. Even a single AA battery 1.5 volt can power up this lamp. Good for survival and if you are living in remote area few of AA batteries could give some good lighting in your house
