Many flashlights, especially penlights do not focus their light effectively, This causes the light to be diffused and the flashlight to be useless. This instructable will show you how to build a cheap and easy reflector so you can focus your flashlight's light more effectively.
First, here is the theory behind the project:
When light is emitted from an incandescent bulb or an LED (less so for an LED) the light spreads out in multiple directions. The purpose of a reflector is to redirect the wasted light and concentrate it, thus making the output of the flashlight brighter.
