Step 14Cook up the power source.
I ended up settling on using surplus Lithium Ion batteries for this project. I use two 8 volt cells in parallel.
Apply flux to the battery leads and solder down your wires to the terminals.
A side note:
If you dont want to use these batteries, you can use conventional NiMH batteries. Your local electronics shop will carry holders for them.
While the LEDs are soldered to take around 12 volts at about 33mA, I found that I could drive my LEDs at a brighter output with around 16 volts at 41mA. Mess around with it.

(http://www.ngineering.com/LED_Calculators.htm)better to do the math. Do not exceed max V or mA raitings on the LED's this shortens life for brightness. better yet use a IC LED Driver for 80-90 efficiency, long battery life and LED's last tens of thousnads of hours.
