Here's a link to a video I uploaded not too long ago. This video is just to show what the finished product will look like. So here's the things you'll need:
-Aluminum construction lamp
-Light bulb (I went to ACE and got a 40Watt refrigerator bulb for $2)
-Cheap wire extension (Lowe's has them for $2)
-Fluorescent starter(s) (Get the FS5. You can find these in the electrical section at Lowe's right next to the long fluorescent bulbs)
-Exacto knife/Utility knife
-Wire cutters (or scissors if you don't have cutters)
-Soldering gun, solder, or electrical tape
Step 1: Lay out the wire extension and cut one side of the wire in half.
Step 2: Strip about a half inch to an inch of the wire on both ends.
Step 3: Take out an FS5 and wrap one end of the wire around one knob and the other end around the other knob.
Step 4: Solder the wires so you don't have any exposed wires. Or you can just use some electrical tape and tape it up.
Step 5: Screw in your light bulb, turn it on and wa la, there you have it. You should now have that creepy flickering light effect. It's cheap, easy, quick and is an awesome effect! Hope you enjoy it and found this helpful
