Picture of Jellyfish Lamp
Hello, this is Aaron Wasserman, Customer Service Rep here at Elemental LED.

This Jellyfish Lamp, which now proudly sits on my desk and keeps me company, was my first attempt at working with LEDs. So if I can do it, so can you!

Basically, it is a purple light made of translucent materials that "glow" as the light shines through them. Although it took about four hours to build, the step that takes the longest is making a structure that looks like a jellyfish. Besides that, all you have to do is string up the lights and turn it on.

Let's get started!

Step 1: Materials Used

4 x 6 in LED Light Bar Extension Cables

4 x 12 in LED Light Bar Extension Cables

2 ft UL LED Strip

2 ft LED Lamp Wire

1 DC Wire Plug

2 x  Female DC Wire Plug

1 Mini RGB LED Controller

1 12V Adapter

1 RGB Strip Light to Bar Connector

1 x plastic strip light spool

1 x plastic to-go container lid

1 x Ziplock Bag

2 x long Ziplock shipping bags

10 sheets of packing bubbles (multiple colors optional)

1 x Hot glue gun

3 x Hot glue sticks

Step 2:

Picture of
If you buy a spool of light strip from Elemental LED, it comes on a white plastic spool. If you don't have one of these, you can use some wire from a coat hanger or something else that you can bend into a round and sturdy shape. I used the spool because I like reusing materials instead of throwing them away if I can help it.

Start by cutting off one side of the spool support (the four arms coming off the center with a ring). This will leave you with a central piece and the other four arms and a ring. Be careful when cutting so you do not split the rest of the piece as the plastic is very brittle. You might have to file the edges of the ring down to dull down any sharp edges left from the cutting.

And here is my version:

I would have used 1 switch instead of 2 and more LEDs, but my budget was 0 and I made this one using only stuff I had lying around.
Building mine now, only uses 2 LEDs and is about 10 cm in diameter. I will make an instructable of it and share the link in comments.
I have a doubt, in what step did you put the leds??

Step 13
i dont see what the tentacles are. but you could make some into lighting strips aswell. that would be cool
Elemental LED (author)  curious youth2 years ago
They were made out of our waterproof extension cables which you can see here: but yeah strip lights could definitely work - if you make a version of a jellyfish lamp - let us know :)

Very cool. I would change a few of the materials to make a cleaner, more efficient design though...
Elemental LED (author)  mochimaster2 years ago
Thanks! Let us know if you make a variation on it. Would be cool to see.

What is that "strip light"?

I think it would have been better to provide a complete list of materials at the beginning of the instructions.
Elemental LED (author)  motleyjust2 years ago
Thank you for bearing with us as we are new to Instructables! I just updated with materials that were used including links to the products we provide on our site. We will do our best in the future to make our step-by-steps easier to follow.
Thanks. That helps a lot.
Click through to the instructor's company (up where it says "Check out our site", which is a link), and you'll see that they sell LED strip lights, among other LED gear.
But, It doesn't say that in the directions. It would be easier for people, just to give a list of materials, the way most instructables do.

My suggestion: Use colored plastic to cover the jellyfish body (e.g., photography gels, colored cellophane, or "festive" cling wrap), then use white LEDs in the body, so the lamp is a functional desk lamp.

Alternatively, use a multi-position rotary switch to let the user choose usable white light versus moody blue light.

Thank you for helping out by suggesting alternative materials. Really loving the response from the community as this was our first project published!

Okay. Another "must do" project for my studio!

The list is getting rather long, but I think this one will get bumped to the top.

Great job!
Elemental LED (author)  mckeephoto2 years ago
Awesome! Be sure to let us know when it's up!

Beautifully done - kind of has an "Encounter at Farpoint" look to it. Very cool!
Elemental LED (author)  browfurd2 years ago
Excellent comparison! Live long and prosper, sir. V ^___^
Well done! Very cool!
Elemental LED (author)  porcupinemamma2 years ago
Thank you very much!
That looks so neat! Good reuse for plastic, too. :D
Elemental LED (author)  jessyratfink2 years ago
Ah thanks for noting we forgot that part. The tentacles are made of our LED Light Bar Extension Cables. Aaron cut each one in half and then glued the connector ends to the underside.

What a beautiful soft blue color!
Elemental LED (author)  finist19772 years ago
Thank you! IRL when you look closely the light pulsates a bit and almost looks like it's moving.

Awesome use of creativity. Love the Blue
Elemental LED (author)  Flying Ace2 years ago
Thank you! Yes, the blue is a calming color.

Thank you :)

This looks very very cool!

I like the fact that it uses a lot of recycled materials.
Elemental LED (author)  janw2 years ago
Thank you very very much! :) It is important to us to incorporate recycled materials in our projects when we can. Didn't hurt we always have extra packaging material lying around the office!

Very informative!

LED lights are very in now days as it saves electricity as well as cuts down our electricity bills. We can replace bulbs and lamps with LEDs.
Elemental LED (author)  johnsena102 years ago
Yes, we love hearing how other people are excited about LEDs as much as we are!
