Question

Answer 1

Hi intensity leds are the answer. The car battery will work but you will need to regulate the voltage to2.5 to 3 volts. This can be done with a simple transistor voltage regulator at radioshack. Follow the diagram on the package. Once you obtain the right voltage, wire all leds in parallel

Answer 2

a car battery and a small inverter.  The inverter cost $30 and use the battery from your car.  An extension cord, $10.

Answer 3

listen,i bought a self power penlight .no battery,even no source of electricity

Answer 4

In small groups,batteries like Ni-cd,or li-ion in the 500 to 1000 ma/hr

could Incorporated. these could also be recharged from small,inexpensive photovoltaic pannels.

using the solar charging aproach, you could maintain a deep cycle

storage battery that would power all of the leds.

this would be a little more pricy.
