In this Instructable I`ll show you how to reuse old lightboulb to make them "run on" LED.

It`s FAST, EASY and CHEAP!

## Step 1: Gather Materials/tools

Look on the photo to see what you need!

## Step 4: Mount To...

This is where the string and eye screw is used !

## Step 5: The END --- TADA!!!

Thanks for looking!!

Questions, constructive criticism and criticism is very welcome! :)

I hope you enjoyed this instructable!
<p>Thanks, I'll be using this very soon :D</p>
<p>OK that is pretty nice but can you make a video on it please? Thank you!!</p>
Don't forget the current limiting resistor in series with the LED, or the LED will burn out. This is an interesting way to dis-assemble a light bulb from the back end without removing the screw-base! Good idea... but I would fill it back up with epoxy or something after installing the LED's just to hold wires in place. Don't forget to wear safety glasses anytime drilling or cutting or messing with glass.
I don`t i understand what you mean with &quot;Don't forget the current limiting resistor in series with the LED&quot; ?? <br>I did not use safety glass but I had the bulb in the plastic bag, it worked fine! But I agree with you that safety is important! <br> <br>
Hello dagelias.... LED diodes should NOT be connected directly to a voltage source because they will burn out quickly. This is because LED's have a maximum current of aprox 20 Milliamperes (equal to 0.020 Amps).<br>If a 500 Ohm resistor was placed in my diagram at R1, then the current would be calculated to be Volts divided by Ohms. If you always calculate using WHOLE units, then your answer will be in whole units (not micro or milli etc). so... 12 volts divided by 500 ohms equals 0.024 Amps. Thats equal to 24 milliamps. 24mA is too much. The diode lifespan will be shortened, and the diode may overheat. If you place NO resistor(zero ohms for R1) in the circuit, the LED will burn out very quickly... maybe instantly. So lets try a 750 ohm resistor: <br>We still have 12 Volts.. divided by 750 ohms equals 0.016 Amps. Thats only 16 milliamperes so the led will be almost maximum briteness and not over-current. This calculation is a little more complex when you use the newer modern HIGH brightness LED's because they have a 2 to 3 volt &quot;voltage drop&quot; across them There are other instructables here on this site that go into better detail about selecting a resistor for your circuit (depending on what kind of an LED you are using). <br><br>About the plastic bag instead of glasses to wear, .... Thats a good idea, i have done that myself when working on a long fluorescent bulbs. Hope this helps.
Beautiful , nice work
thanks :)
