18AWG Low Voltage LED Cable 4 Conductor In-Wall Jacketed Pure Copper Speaker Wire UL/cUL Class 2 (50ft. Spool)

I only found out there is a problem with this wire while I was cutting lengths of it to make leader wires for my speaker selector switch. About 20 feet into the roll, the green insulated wire was BLACK instead of copper colored. I could scrape the black junk off of the wire. It was crusty.After finding the black wire, I cut into the rest of the wire in various places. I found at least 5 feet of the green wire was black. Black indicates defective wire. There is no telling if there are other segments in the same conductor, or even other conductors which have the same issue.I wasted about 2 hours of my time because now I have to order more wire and start over again. I don't trust the quality of the leaders because of what I found.

I bought this for connecting up high power RGBW LEDs, and it's nice to have insulation colors that match the usage. Other vendors sell similar cables tagged for audio use that generally use a black wire instead of either the green or blue wire, which is sufficient to keep the wiring consistent, but can introduce some confusion. I wish this was also available with another outer insulation color; I would buy both to separate positive and negative connections. I can make do by marking or adding shrink tubing to one side.[Edited] Now having used some of this wire, I've examined it more closely. Unlike other similar 4-conductor CL2-rated wire, this has thinner, less substantial insulation that appears to melt much more easily at soldering temperatures. The wire itself, while it appears to have a similar overall diameter compared to my other 4-conductor 18AWG wires, is made from approximately 20 strands of copper wire, while my other wire has more than 40 strands of thinner wire. I haven't tested this wire for fire rating nor measured the gauge of the strands or resistance/length, but it appears to be less robust than other offerings.

Used as speaker wire for surround sound speakers. Easily hidden along baseboards using small cable clips. Make sure to buy long length. Mine came up a little bit short. Better to have a little extra wire. Nice being four conductor. Makes for a nice neat installation. Recommended.

I use this wiring to run led lighting in residential and commercial applications. The cable is high quality and well shielded. It’s a little tough to solder onto the led strip because the gauge is much higher than most but it’s possible with some patience

I can't say I was pleased overall. I bought this last year to wire up my Christmas pixel lights. The jacket is very thin and loose, so when pulling the cable, it will pull the wires apart on the other end. No matter how careful or what wire strippers I used, they would always cut right through the jacket into the individual wires. It twisted so easily, causing long runs to bunch up. I ended up tossing the box out. Failure rate was too high.

Very convenient, and clean way of running led cable. Seems good quality just wish it was shielded as I’ve got it running next to a audio feed wire and I’m getting a lot of cross talk. (I know I should use shielded audio wire but it’s not what came factory on my truck and replacing all the audio wiring is not something I want to do.)Would buy again if I had a different application to use it on.

Used this to wire an external 8" sub to a 2017 Jetta with a stock radio using the low level input. Much easier to use this than conventional speaker wire and works just as well.

Looked like it was less than 18 ga. but I guess it's ok. Its like lamp cord wire. Using for small, auxilliary speakers.Seems to work just fine.
