Circuit Building Question - I need an Electrician / Circuit Guru?
I need to achieve the following and need to know the best way to do it:
I have a 3.6v led light cap (for flashlight) and also have a 2-prong-To-light bulb end (metal screw part) adaptor. The 2-prong end lets you plug a regular 2-prong power cable plug into the 2-prong female end and then screw it in to any lightbulb outlet to draw power.
I know one of you mad scientists know how to connect these two pieces together by creating a circuit in the middle to convert the 120v light bulb power to safely power the 3.6v multi-led light cap.
Please describe each piece you would use to do this and how they are connected.
I would be EXTREMELY grateful if you can please help me figure out how to do this.

Why would you want to do this? This is more complicated than you think.
PS, insults will not help you get a good answer !
the way you connect to the 120 VAC is irrelevant. light socket, light socket adaptor, wall outlet, they all supply 120 VAC (240 in europe).
Missing is the current requirements for the LED, so details cannot be provided.
there are several alternatives. One is a transformer, with a 5 volt secondary, rectifier and resistor. You have to pick the values, buy them, wire them together.
another alternative is to buy one of those small "wall-wart" type supplies. these are small about 1 or 2 inch cubes that plug into an AC outlet and supply a DC voltage. Get one with 9 or 12 volts output and enough current to light the LED (don't know what that is), then put a resistor between it's output and the LED.
The other alternative is a large power resistor and diode to drop the 120 VAC (240 if you live in europe) to the low voltage needed for the LED). the resistor will be big, and hot, and will waste a lot of power.
