I used an upturned 50mm fold back clip to help hold the cable in place. You might find a clamp to hold your wire and/or circuit board helpful for this. I bent them around to help hold them in place while soldering. I then threaded the red wire from the USB cable through the positive side on the circuit board, and the black wire through the negative. Note in the picture you can see through the holes. Later on I ended up completely removing the battery terminals from the battery holder (they might come in handy for another project later), so I could have left the wires connected on those.Īfter that I made sure the circuit board was clean enough for new connections from the USB cable. I then desoldered the connections from the battery terminals to the wires, though you could omit this step if it suits. So using the soldering iron I desoldered the connections from the battery holder to the circuit board. For my purposes however, I didn't care about using the battery capability any further. NB: if you want to retain the ability to use a battery in your lamp, you'll need to omit the part about disconnecting the battery terminals. Step 3: Remove the LED Assembly From the Lamp Next I will get the LED Assembly ready and connect the wires. I don't know the exact purpose of it but I don't care either - only the Red and Black wires are important for this conversion.

Your USB cable should have a minimum of 4 wires in it, being: You could remove the Green and White ends now if you like or you can snip them off later. The red and black wires should have a small section stripped as well, and if necessary twist the exposed wires into a nice neat strand. Then if you have wire strippers, now is a good time to use them to strip a small length off of the end of the USB cable, remove any shielding in place and separate the wires.
