Protector Circuit? Answered

How can I make a circuit that will protect an LED when I plug it into a traditional light bulb plug?
 hint- homemade LED light bulbs.

 You have to see what the power requirements are of the LEDs that will be used.  I pretty sure you would have to first drop the voltage from the mains and then limit the current going to the LED.  Look up some LED instructables that use transformers for power supplies.  Good luck.
