One day while walking in the street, I saw this "UFO LED Lamp" in the display of a lightning shop, and fel in love instantly with it.
Usually, lights ... well, actually, there are so many shapes for lights, that there is no rule, but I'm pretty sure that before LEDs (at an affordable price) came into the picture, lights were big. Not big big, but certainly not flat.

Now with LEDs, a lights can be fairly small, and flat, but this light that I saw in a store's display window was for me the first one that really used the possibility to make a light flat, not just to win space, but to create an effect that I will describe as follow: "to create light from nowhere".
Since I was so attracted by this light, knowing that I had no "need" of it, and that the price tag would everything but flat, I decided to try to reproduce it myself.

This might be my first instructable, but I've always loved to look at other peoples creations here since a friend of mine gave me the link to his own first instructable (Multi-purpose-holder-from-kitchen-whisk ), and I hope this one won't turn out too bad.

Step 1: What to make it from?

The light that I saw in the shop seemed to me to be using strong LEDs, which I believe are quite hot, meaning that there could be some heat dissipation issues, and also glass, which is not the easiest thing to work with.

For the LEDs, the solution kind of came to me on its own. At the time, I was moving into my first real own flat, after living for two years in a great share-flat in Brussels. Moving into a new flat usually implies some trips to Ikea, and I was of course no exception!
So it is there that I discovered those light strings, which sadly were not anymore available last time I checked, called "glänsa".
Each strings contained 144 LEDs, which seemed to be a good number, and happened to provide not a powerful light, but a glow strong enough to get a nice feeling to a room. I really don't think it should be used to read, or for any other activity being stressful for the eyes.
So I bought two of those.
I already knew then that LEDs can be expensive, and also that since I have no real knowledge on how to make a LED light, I was just better off hacking one.

Then I spent a lot of time thinking on how I would reproduce this "disc", with all the drilling that was going to be necessary.
When I say a lot, just know that the picture shown in the intro step was taken mid november of 2010, and that I finished the light today, june 19th 2011! So it has been some time, but the thing is that I settled for plexiglas. Two pieces of plexiglas actually.

My idea was that to "create light from nowhere", I would be using some king of reflective material to make sure that all the light emitted by the LEDs was going to go in the same direction, and then something that would also unit the glow of each LED, to give the shape to the light.
So when I knew that, I found a professional website on Internet, selling a lot a different kind of plexiglas, ordered a few samples, and then the real thing.

Those are the only thing I had to get, beside tools (and the hooks actually). I paid around 80€ for the plexiglas, and I think one light string was 24€.
Phil, what is your power supply and current rating
Hi,<br>The AC adapter specifies 24VDC 6VA, but since the adapter came with the LED strand, I could not have got wrong.<br>Right now the lamp is leaning against a wall so there is no aesthetic issue with the AC adapter, but if some day it goes horizontal, maybe I'll change for something more flat. Until then, I really prefer keeping the original hardware.
muy bueno, con que voltaje trabaja la lampara ... graias
actually everything is much much easyer... but much more expensive... tip u need CNC and neon light around.
--I can forsee an RGB version in my future!!! <br>Nice work!!!
oooooh, with several different 'zones' and an arduino controller......many many possibilities,,,,,,, <br> <br>sound responsive, animated, changing color to a 'RED ALERT' <br> <br>so much fun to be had with this
oh wow i need to make one of those
That last picture, where it &quot;hovers&quot; is especially impressive. Great instructable, thanks!
