Fixing low voltage copper wire LED strings.


This video is about repairing the very common low voltage (3 to 12V) LED strings based on insulated copper wire with LEDs soldered across them and dipped in resin. The guide is not suitable for traditional mains voltage LED strings.
I like the copper-wire LED strings. It’s a simple parallel circuit of voltage matched LEDs that are quite rugged and water resistant by virtue of the LED and wire connection points being dipped in resin forming a strong bead on the wire. It is possible to snap the wire though, and I often get asked if it’s possible to repair or shorten them.
The simple two wire parallel strings are also ideal for chopping into shorter sections for other applications.
