CD Light Reflector
make a light reflector from an old CD. I got the original idea from http://www.pencildude.com/tips/oldcdroms.html
Cut a hole on the inside of the CD using a sharp knife or a hot blade. The diameter of the hole is equal to the diameter of the lampholder. in the figure, cut along the blue coloured circle.
Just Slide the CD Onto the Inside of the Lampholder.
Just slide the CD onto the inside of the lampholder. No glue is necessary. Fix the the bulb onto the holder
Switch on the Bulb!
just swtich it on.
