My feeling is that these are some kind of “smart” LED being used - possibly addressable as the power pack has options for various chasing sequences, yet is connected to the set with just 2 wires.
#Led icycle lights series
Once shortened I was planning to add several 1N4148’s in series at the cut points to overcome the additional voltage presented to all the remaining LED’s. Several of the LED’s also have 5/6 incoming wires connected. LED Icicle lights feature M5 LED bulbs and come in a variety of bulb counts and colors to accommodate any lighting project. Whether hung from the roof or dangling from your patio overhang, they bring a dynamic, warm layering of light to the space. LED Icicle Christmas lights allow you to plug over 15 light strings end to end without worry of blowing fuses, all the while lasting 10 times longer than your old filament style bulb strings. And, since they burn at a lower temperature, LED icicle.
These led twinkling icicle lights have copper wirings and uniform brightness. LED icicle lights use less energy and last nearly 20 times longer than incandescent icicle lights. Lighten special occasions even more with the powerful led twinkling icicle lights on. If you’d rather have a cool glow, opt for LED icicle lights. It almost seems they’re all in series, but guessing with a volt drop of about 4v per LED (white) then the PSU voltage should be 3.2Kv! I expected a small section to die when cutting wire A, as this would suggest a sub-parallel section, but I just can’t figure why ALL go out when cutting B or C. Composed of strings of M5 mini-bulbs of varying lengths, LED icicle lights lend beauty and elegance to any display. Incandescent icicle lights give off a warm glow and are a cost-effective solution, but they can heat up with extended use. So having read that these type of lights are normally wired in series/parallel arrangement I’m puzzled why the whole lot dies when I cut either wire B or C, as I’d obviously expect the ones prior to mostly all stay on. Durable, last longer and use up to 90 less electricity than their incandescent counterparts. I marked the 3 wires and cut each in turn with differing results - LED icicle lights line your roofline to take advantage of the latest in technology partnered with a traditional Christmas light style. Running along the main “backbone” are 3 wires, then there’s lots of drop-down strings to give the icicle effect.
The lights are 22 meters long and I’m wanting to shorten them to 20M, it’s an 800 LED string so I’d be losing about 40 LED’s. I have a set of outdoor Christmas icicle LED lights that I’d like to shorten and wondered if anyone could help me please with the way to do this? I thought it would be a simple job but there's something odd about the way it's wired.
