[UVAA] How to make a red night light

Hello All, For anyone that wants to make a red night light to use while star gazing, here is an cheap way. Red plastic celephane does NOT work; too much white light still gets through. A thick, red plastic cup works perfect. Just cut the bottom out of a red plastic cup. It works perfect! If you unscrew the top of a flash light, there is a regular, clear plastic cover above the bulb were you can place the newly-made red plastic insert. You can buy a cheap flashlight at the Dollar store. Sean Humpherys
