Smallest 1xAA (14500 or 18650) Flashlight for < 20$ ?

[cpu]

Hi, I'm looking for a real cheap, real tiny flashlight (quality of the light is not important) that can hold a large capacity rechargeable battery like a TrustFire Protected 18650 Lithium Battery (http://www.dealextreme.com/details.dx/sku.5790) or two Rechargeable 3V CR2 800mAh batteries in series (http://www.dealextreme.com/details.dx/sku.932).

I really just need to fit a lot of battery juice in a tiny package. (I don't intend to use the light at all, as I'm going to modify this flashlight for a different project).

Any suggestions would be greatly appreciated!

well 18650 lights will be significantly larger than AA/14500 Lights. A relatively small and cheap 18650 light is the tr-801 at dx sku 13095. An 18650 battery will hold significantly more energy than a 14500.

Then you dont need a flashlight, you need a battery host. Use a pvc tube :twothumbs or this.
