So i was looking for a couple of lamps for my bedroom, i had in mind something industrial, hanging lamps would be the option. i started looking on amazon and many other sites, although most of the "industrial" lamps look really nice, they were not really industrial, either too elegant to be industrial or scaled to be smaller.

This situation lead me to create my very own lamps, and you can create your own as well, here's what you need:

2 x Old Industrial Lamps (got them from a industrial dump for $20.0 USD).
~20m heavy duty electrical wire.
6 x pulleys
2 x Ceiling hooks
2 x Wall hook
2 x Wall cord hook
2 x Light bulb sockets
2 x Light bulbs
1 x Electric plug
1 x Light switch
Pipes and connectors (explained latter)
Anchors and screws (depends on your wall/ceiling materials)
Black flat paint (optional)
Willing to unassemble old dusty lamps and lots of patience

Step 1: Find the Lamps

I thought this was going to be really complicated but it was absolutely the opposite , i went to an industrial dump and the first thing i saw was the lamps, instead of paying 50~100 USDs on amazon i paid 20 USD for both old lamps.

Step 2: Unpack and Disassemble

The funniest part, disassemble everything.

I took apart the cover and started to disassemble every single part, i took away all of the electrical components as they were burned or too heavy for a residential deployment.

At the end, the parts i was going to use were something about 20% of the original weight.

Step 3: Wash the Usable Parts

After deciding what was going to use and what not, i washed everything to take away all the dust, then let everything to dry pretty well.

Step 4: The Lamp Hook

The most complicated part of the final design was how to hang the lamp itself.

The lamp came with a hook that passes the wire in between, however, it couldn't be directly attached to the lamp, it was supposed to use another component that was out of center because of the weight distribution of the original components, if i would use it, the lamp would hang bowed.

Therefore, i had to use many different parts to create a hook that can pass the wire and hang the lamp at the same time. i took the original hook to lowes and i found everything right there.

Step 5: Paint

If you prefer the original look you might avoid this step, i just thought the lamps would look better with a flat black tone.

I decided to paint the screws as well, i used a card box so it was easier to paint them, make sure you push all the way to the bottom to paint only the heads.

Step 6: Counterweight

Once you have the final components of the lamp put everything together (not necessarily assembled) and measure it on a scale.

As you can see on the image, the weight of B (the lamp) has to have half of the weight as A (the counterweight).

In other words, the counterweight has to have twice the weight of the lamp. (Thanks @UCN for the clarification https://www.instructables.com/member/ucn)

I went to the same industrial dump where i got the lamps and found a bar of metal with the specific weight.

Step 7: Measuring the Wires

To make sure how much wire do you need take the following measures:

A - B: The distance between the power outlet and the light switch.

B - C: The distance from the light switch to the top of the wall.

C - D: The length you want the counterweight to hang

D - E: Same as before.

E - F: The length of the final lamp.

B - G:The distance between the lamps (in my case, my bed)

Step 8: Lamp Assemble

When everything is nice and painted, is time to assemble!

First pass three of the pulleys per lamp wire, we're gonna use them latter and we better have them in place at this time.
Use an adjustable clamp to create a loop, this is where the lamp will hang from.
Close the lap's box (it is empty at this point) passing the wire trough.
put the shade on place and add the counterweight to the assemble.

Step 9: The Electric Part

As you can see, the electric circuit is quite simple, i don't have any experience as a electrician and i was able to do it following a couple of videos on you tube.

On the first image:

A is the power outlet
B is the light switch
C are the lamps

I used a "bticino" box, switch and cover. also i placed plastic bumpers on the button to protect the wood on my night table.
Mount the light bulb sockets at the button of the lamp.
Put the lamp shade on place.
Connect the lam's wires to the switch.
Keep everything together with an adjustable clamp

Step 10: Wall and Ceiling Preparation

This step is going to depend a lot on the hooks and wall/ceiling material you have.

Make sure you have the wall cord hook at a certain height that you can adjust latter as you wish.
Consider the diameter of the lap's shade and the distance to the wall for the hook on the ceiling.
Make sure the hook on the top of the wall is co-lineal with the wall cord hook and the ceiling hook.

Step 11: Put the Lamps on Place

Once you have everything together is really simple to put it on place. i started with the pulley on the top of the wall and keeping the wire as long as posible, then the pulley on the ceiling. finally adjusting the counterweight. ta da! from trash to treasure.
