Picture of LED Light Globe Hack
Hack an LED screw globe and make it portable.

I recently got my hands on an LED globe which came with a remote.  After a lot of use in the kid’s room it finally stopped working.  I think the reason why is that they have a dimmer in their room and the LED globe didn’t seem to like it too much when it was dimmed. 

Instead of just throwing it away I decided to see what was inside, and if there was any way that I could hack it to make it portable.  Well there was a way and here’s how to do it.

So if you ever have a need to turn a room blue, or like the look of the red light district – then this project is for you!


Step 1: Parts to Gather

Picture of Parts to Gather

1. LED Globe – Ebay
2. 9v battery
3. 9v battery terminal - These can be purchased at any electronics store (or scavenged from a broken toy)
4. Wires
5. Toggle Switch – Ebay
6. Box.  This could be anything that the battery can fit into.
7. Heat-sink.  I used a video card one from an old PC - Ebay
8. Screws


1. Soldering iron
2. Pliers
3. Wire cutters
4. Sharp scissors
5. Screw driver
6. Phillips head
7. Drill
8. Hot glue


How long does the standard 9V last? I'm thinking of modifying the use rechargeable AA's instead.

what i mean to say is when i turn on the switch on the side it just starts flashing through colors. what should i do?
Try making sure the battery in the remote is not dead, or the paper is not separating the connection if you have not used it before. Also, distance matters; too far away and it won't send the signal.

Would love to see another method of control other than the Commercial remote. Overall I like this conversion.

I do wonder about the need for a heat sink. It would be interesting to measure the temperature inside the box both with and without the heat sink. I also wonder if some larger, ni-cads or Li-ion batteries wouldn't be a better choice. Those 9V batteries are expensive.

I did hook-up the led's without the heat sink and those puppies do get hot. You could probably get away without having one but i think it looks pretty cool with it.

Re-chargeable batteries would be a good idea - you could add a plug into the back of the box to charge them.

the 9v battery I used was about $5 so not too expensive really.

Great Instructable!
is there an award for best accompanying music? this should win.
who's on the flute?

I'm confused.. i got mine to work but the remote simply will not work. it just started on its cycle and won't change to the color i want... did i just rip out something i wasn't supposed to?

Hey there,
Not too sure why that would be happening. Have you tried to remove the battery and attach it again? Make sure its a new 9v battery. There isn't much you can rip out as the circuit board is one complete part with just a couple of wires sticking out the back.
Are you using the same light as I did? If not, maybe you need 2 9v batteries to get it running right. Check your wiring again and make sure that nothing is short circuiting.
Hope you can get it to work!
This is super awesome! I had an idea just like this but it uses LEDs powered by an Arduino.

Nicely done, I am adding this to my list of my next 'fun projects' !!

Cool Idea, was it the same LED bulb that you won in the Lamps & Lighting contest :)

Yeah is was! Good memory Tarun.
I won a couple of them so I think I might hack that one as well.
Awesome :). I remember things I admire, I just loved your PIR airplane hack.
