Step 1: Getting Ready

Before you start making your own lamp, you should collect some parts and check if you have all the required tools.
Don't worry, most likely you have most of the stuff already. If not, they are easy to find at a very affordable price.


How many CDs do I need?
To build a lamp of the suggested size, you need between 900 and 1000 compact discs (around 15Kg).
In case you don't have such amount of old CDs, spread the word around your friends, schoolmates, co-workers: they will be enthusiastic about getting rid of their old crappy CDs (e.g.: old music from the 80s, magazines freebies, burned copies)

The other stuff

Circle of MDF wood
diameter 20cm / height 1.5 cm
easy to find at bricolage stores

Electrical connectors
12 connectors
The size of the connector should be determined by the diameter of the iron wire: the iron wire should fit in the hole of the connector

Iron wire
5 mt of diameter 2mm iron wire should be ok

Lamp holder + electric wire + switch + plug
You can easily find a pre-assembled package or you can build your own. Choose electrical wire size and style according to your preferences. I would recommend at least a 2 mt wire

E27 energy saver fluorescent lamp
Any regular energy saver (e.g.: E27 7-11 Watt) fluorescent lamp would be ok. If you like to install a smaller size lamp, make sure you buy the correct lamp holder accordingly

Silicone sticks
Makes sure you buy transparent silicone, take 2 large size sticks

Rubber feet
3 pcs.
tiny rubber feet should have approximately a 2cm diameter


The toolbox
Most likely you need a small set of common tools:
* driller
* claws
* pincers
* screw driver
* glue/silicon gun
* compasses
* pencil
* square ruler
* cutter

Step 2: Making the Bottom

Take the MDF wood circle and using the compasses and ruler divide the circle into 12 sectors.

Trace with the pencil the points for inserting the lamp holder, the iron wire  and the rubber feet as shown in the picture (photo of the bottom with measures)

Use the driller to make the hole following the points traced with the pencil

Cut 6 pieces of iron wire using the claws, 1 mt each
Curve each piece as a U shape using the pincers like shown in the picture

Now you have all the pieces to assemble the bottom, proceed as follows:

1) mount the 3 rubber feet with screws and screw driver
2) mount the lamp holder in the central hole

as a result you should see the lamp holder in the center

Step 3: Making the Cage and Preparing the Sphere of CDs

mount the 6 U-shaped iron wires by inserting the two wire endpoints into the holes

now you should curve the iron wires using your hands and the pincers

shape the cage of iron wire like a sphere (SEE PICTURE)

cut the exceeding iron wire with the claws

as a result you should have a regular grid of 12 iron wires shaped like a spheric cage (SEE PICTURE)

Now you can start making the piles of CDs

At first you have to fill with CDs only the 6 piles of CDs that are closer to the center:

place alternatively a layer of 3 CDs through the iron wires at a time (SEE PICTURE)
each CD should be placed on top of the adjacent two CDs
every 5-10 layers make sure the CDs are placed regularly and fill in the space between the hole of the CD and the iron wire with silicone using the glue gun

repeat this operation until the the adjacent curved piles of CDs do not overlap, this should be when each pile of CDs is about 6 cm tall

at this point you start placing alternatively 6 CDs per layer (SEE PICTURE)
like before, every 5-10 layers fill in the space between the hole of the CD and the iron wire with silicon
as a result you should build 12 piles of CDs

repeat this operation until 12 CDs won't fit any longer, then start again placing 3 CDs per layer like before
the 6 piles of CDs should converge towards the center and the central hole is too small, do not forget to install the E27 lamp

important:
* for the last 5 to 10 layers do not use silicone, so that the lamp can be unmounted to change the lamp
* while placing the CDs you should check and curve the iron wire to make sure they keep a regular shape

Step 4: Preparing the Top

when the height of the structure is about 26 cm you should curve each iron wire towards the center
cut the exceeding wire using the claws
as a result you should have something like in the PICTURE

now it's time to prepare the circle for locking the 12 iron wires
divide a circle (e.g. two overlapped CDs) into 12 sectors
on each radius trace the 2 points for installing the electric connectors
use the driller to make the 24 holes
make sure the distance of the 2 holes on each radius is compatible with your connector

disassemble the electric connector and extract the 12 metal connectors

mount the top placing each iron wire end through the electric connector and lock the screw with the screw driver

Step 5: Enjoy Your New CDs Lamp

Now it's time to enjoy your beautiful CDs lamp !

zomgoggle wow! I'll bet it's heavy! But so cool. It would make a cool chandelier but I'll bet it's heavy.

To: samimy -- the lamp has been on for an entire night, no issues with the cds so far. I initially thought the same but actually energy save lamps are ok

author
Samimy (author)2013-04-10

your idea is cool, but the only problem is that type of UV-Lamp you have used is the
getting hot one.
i mean it gets hot after an hour and may burn the cds.
LEDs were best choice for this project though.

This is the best CD lamp I have seen so far. Great Design. Thanks for sharing.

ironsmiter (author)2013-04-09

and i thought the stacks of 100, with the ccfl in the middle was a lot of discs to stack.

Nice job on the design.

nice job! One 1., how would you change the lightbulb?

author
uncellfish (author)cbadzioch2015-05-15

you pray to never do that :-)

besides jokes, it is not too difficult, the cds on the top are not glued, it is relatively easy to unmount and extract the lightbulb

I'm never gonna do this myself, but this is the coolest looking lamp and use of recycled CD's I've ever seen! Awesome creativity!

This is a good design but I think that is a heavy lamp.

Very well done. Thanks for sharing. As a CD lamp maker myself I think you did a wonderful job. I like the design.

I never had issue with heat with my CD lamps either.

Silicon is a hard shiny element. I think you mean silicone in your parts list.

author
uncellfish (author)JayGeeBSE2013-04-11

you are right, typo corrected, thanks

author
JayGeeBSE (author)2013-04-11

Basic safety failure. You have mains wire trapped under an accessible piece of unearthed iron wire. If it crushes through the insulation the whole construction becomes live. Either you should have more protection for the mains wire or the iron wire should be earthed. I'm not sure about the aluminium coated discs - they might conduct a shock too.

author
uncellfish (author)JayGeeBSE2013-04-11

good point, I am going to protect the iron wire, thanks

Ok looks good but It must be way heavy with the mdf plus 1000 cds

author
wagnerduro (author)2013-04-11

900 and 1000 compact discs (around 15Kg)????
No, it's madness. low luminous efficiency for too much things...

author
Blackice504 (author)2013-04-11

cool i now have something to do with the 1000's of CD / DVD that are stuffed or scratched, i might try some L.E.D's.

author
uncellfish (author)2013-04-11

That's right, indeed I recommend to avoid silicon for fixing the last layers on the top

author
Xieda (author)2013-04-11

I take it, from what I could see of the design, that changing the lightbulb is not possible without deconstructing the majority of the lamp, yes?
