Hi Michael,

First things first, we have a fantastic guide on identifying electrical connectors.

At a glance, from the photos you’ve sent, it’s likely to be JST-RE, or DuPont.

Could you post an angle from the side so we can get a better look at the retention clip?

We sell housings for DuPont connectors, and crimp pins, shown below:

If you weren’t after so much current, you could get away with prototyping wire, but generally it’s far too thin for high powered LEDs such as these.

If you’re just looking to fix the LED that you have, it’s likely the solder joint or wire has fatigued to failure, so you can probably fix it by just stripping the broken wire and resoldering it to the pad on the LED.

If you need more of a hand on any of the processes mentioned here, let me know and I’ll link some tutorials.

Keen to get your project on track!

What is a retention clip ? Which angle photo do you want ? I am replacing not repairing
The original red led light is too dull it needs to be much brighter and white for the kaleidoscope Star and galaxy globe The globe is comprised of black plastic sections with star shapes where light comes out

I’ll need thicker wire to handle the voltage is that correct?

Hi Michael,

The short answer is it’s hard to say at this stage. You’ll need more info before you can make those decisions.

There are two important sets of specifications to consider when connecting any component to a system - electrical and mechanical. Usually the best people to ask about the specifications are the people who designed it, ie. the manufacturer.

If you aren’t just going for a drop-in replacement and you can’t get the details from the manufacturer you’ll need to do some basic reverse engineering first. The risk with changing one thing can have a snow ball effect that requires everything to be changed. Everything in a system depends on everything else, so it can be quite a pin sometimes if you’re deviating far from the original design.

To get started, you’ll need to gather some more information about what you’re connecting it to - particularly:

  • what voltage (Volts) will it be supplied with, and
  • how much current (Amps) is available from the power source.

If it’s a simple supply only powering the LED, these details might be written on it. If it’s supplying other things you’ll need to make sure there’s enough capacity left over to power the new LED (you can just sum up the current requirements of the other things in the circuit).

Then you’ll need to make sure that whatever you’re connecting to that power supply (in this case a new LED) won’t need more power than is available from the supply. FYI, for DC electronics, you can easily convert between Power, Voltage, and Current using P=VI.

As for the mechanical side of things, you’re probably best off reusing the existing connector by soldering the wires to a new LED if you aren’t going to exceed its ratings. If you need to, you could also make up a new connector, or buy a connector pre-crimped to some wires (often called a pigtail). You should be able to identify the connector using the guide James linked above.

You can find guides to the current handling capacity of different wire sizes (usually written on the wire insulation in units of AWG or mm^2) online with a quick google. Once you know how much current your existing wire and connector can handle, and what you need it to handle, you can tell whether you’ll need thicker wire.

For some further reading, we’ve got a really good tutorial on current, voltage, and power here:

A really good article on LEDs here:

And a really good guide on crimping connectors here:

It sounds like you’ve got quite a bit to learn, but it’ll definitely be worth the time investment to gain the knowledge! I know use mine all the time to fix things :slight_smile:


Going a thicker connecting wire is safe

4 X AA batteries is the power source

Going a multivoltage white LED next higher voltage than 6 volt if it’s too much of a jump we try 6 volt but brighter There is no information it’s from China so we have to work it out ourselves The plan is go higher but don’t deviate too much
The original LED was red the wrong colour too dull to even get a shape on the ceiling
We need white and stronger brighter light


Could you please advise what part you have that will be compatible and what photo you need and explain which end iof the photos I sent is the retainer clip thks
