Soldering iron, stand and damp sponge

Black and red multicore wire.

Wire strippers

Solder

Do not forget to wear an apron so that the hot molten solder does not land on your trousers/skirts as it will ruin your clothes and could burn your legs through the fabric.

Do not forget to protect your eyes in case the solder spits or you put the soldering iron near your eyes by mistake when holding it. 

It is important that the sponge is slightly damp.  It should not be wet or have any dripping water.  Squeeze all water out of the sponge once you've wet it under the tap to do this.

Touch the soldering iron on the right and left hand side pads.  Push the solder onto the soldering iron.

The solder will melt and fill up the pad.  Repeat this for both large pads on the left and right.

Strip the wires using a wire strippers.  So that all the wires you strip are consistently the same length, there is a red stop inside.

Pull the trigger and you will see the cable being stripped.

Now twist the black plastic end around so that the cables become twisted.

Place the soldering iron next to your stripped wire and add the solder onto the end of the soldering iron.  The solder melt and flow into the wire.

Place the tinned wires onto the tinned USB pads.

Use the soldering iron to heat it all up and it will join both permanently.

You can see both wires joined permanently.  

It is very important that the red and black plastic part of the wires are on the circuit board a few mm as shown.

Use the glue gun to put hot glue over the soldered pads.  Most importantly, make sure the hot glue is ove the ends of the black and red wires.

The completed soldered LED.  By adding the hot glue, it will stop the wires bending exactly where they have been soldered so they will not snap off when assembling your lamp.
