wiring a light bulb directly to an extension cord
If I wanted to cut off the end of a 3 prong extension cord and solder it direct to a light bulb, which color wire would I solder to the bottom of the bulb and which to the screw-threaded portion of the base ?

Depends on what color wires you have. The one that connects to the middle prong (ground) doesn't connect. The other two wires can connect either way.
Edit: go here http://www.peavey.com/support/techno...hockhazard.cfm And remember, the wires can be connected wrong, so be careful.

Also, this is a bad idea. If you want a light bulb on a cord, connect a socket on the end. Don't solder it right to the bulb.

Yes, ignore the green, and connect the black and white to whichever. This is a terrible idea, however. Just buy an old lamp at a garage sale for 50 cents, or a drop light at walmart for $2 and use the socket from it. Then you can replace the bulb and not start fires or electrecute things.

Honestly it likely won't matter. As long as the element has power running through it it will light up. Try it on a bench vise. You can switch them around touching the white wire to the side and black to the bottom and it will light up without any noticeable difference. But if I remember correctly the bottom should be hot, ie black.
All that said I agree with everyone else, go buy a socket. Open elec. connections are a bad idea. Edit: Here's a diagram: 8- Neg. 11- Pos. But like I said in a basic incandescent bulb it doesn't matter which way the power flows within the bulb itself. As long as 110 goes through that element (#3) it will light.

The big question is why on earth would you want to do something like that? Even more, you want to do that and don't even understand which wires do what.

wtf? seriously?
You know you can go down to the Ace Hardware or Home Depot and buy exactly the interface you want, right? I have one in my toolbox for illuminating dark hallways and closets. It's just a bulb socket with a plug. It's cheap as hell. ... I... uh... damn.

Well, I came home tonight very tired only to find my electric meter gone and the power out in my house. My friend warned me as the town filled up with summer tourists people would move into town and take anything not bolted down, though he told me to lock up my water meter since it's brass. Took me a while to trouble shoot, in the dark, exactly what or why I didn't have power. All the other houses on my street had power. So much for my advice regarding no open electrical connections. I'm not going to detail exactly how I resolved this issue. But standing on a plastic five gallon bucket (doesn't create a ground) I manged to hook myself back up with some #10 wire I had left over from installing my A/C. I'm not sleeping in the July heat down here without A/C.
What a pain. Hooking up 220 in the dark, standing on bucket with make shift leads isn't my idea of fun. I need a beer... and ice. All my ice melted all over my kitchen floor.

Regardless of how dangerous and unnecessary the lightbulb soldering idea is, if you have a two wire cord, the smooth insulated side of the cord would connect to the bottom tip of the lamp, and the ridged insulation side of the cord would solder to the screwshell part. If you have a three wire cord, connect the black wire to the bottom contact of the bulb, and the white wire to the screw shell part - and the ground wire (bare copper or green insulated) doesn't connect to anything at the lamp. The color coding, or the identification scheme on the insulation, only matters when you connect to a lamp socket. The idea was to keep the white wire connected to the screwshell - which has almost no voltage on it during normal installations - and the "hot" wire connects to the center tab down deep in the socket, where people wouldn't normally be likely to be sticking their fingers into it.

The key point in that entire post was "Ex" Mrs. Tully.
I once spent four hours in the driving rain sitting on the second story of my house because she and her girlfriend went shopping. The ladder leaning against the front of the house seemed out of place, so they laid it down in the front yard. Imagine my surprise when I finished cleaning the gutters on the back side of the house. -----Added 14/8/2008 at 01 : 48 : 05----- Quote:
Good duct tape does, the cheap stuff usually doesn't, IMHO. But you're right given a choice I would have used a ton on electrical tape instead. I'm limited as to what available at the local Mexican Wal-Mart.

What can I say- somethings seem more obvious over time. Though to be fair you're only hearing one side of things, I'm certainly not perfect... but yeah from my perspective she's the "ex" for many, many reasons.

As far as 110 voltage goes, the white wire is considered "neutral" or ground in this case. The black wire should go to the center of the bulb, and the white one to the threaded area. However as has been said MANY times, I would highly suggest against this.

i think the point is to save the inevitable the live wire is connected to the left hand and the neutral wire to the right. sockets are very cheap, no soldering required and most ppl survive the experience of dealing with them. are you also the person that uses hair dryers in the bath?

Lindy has the safe and correct solution.
I used to work lights in a theater, and I built three of these to test which dimmer was connected to which plug after each lighting designer changed everything, then left without any idea of what connected where.
