40FT 18 Gauge RGBW LED Strip Extension Cable 18AWG 5pin 5 Color Stand Electrical Flexible Wire Extension Cord for RGBW RGBWW LED Ribbon Lamp Tape Lighting (40 Feet per Spool)

The V+ G R B W order matches the V+ G R B W order of most LED light strips.Heavier gauge wire is better for higher current when running lots of LED's to reduce voltage drop and avoid dimmer LED's at the end of the cable run. Lighter gauge wire (22 AWG) is less expensive than this 18 AWG wire but may have too much voltage drop. The 22 AWG wire is easier to solder to the LED light strips. This 18 AWG cable is better for providing power over longer distances. Connect this to the shorter, 22 AWG leads soldered to the strips.I used this cable and supplemented it with an additional 12 AWG cable for V+ (black) since the black wire must supply the combined currents of the GRBW wires. I used a junction box at each LED strip to make the connections. (See image.)

This wire worked well and has reasonably flexible insulation. There have been questions about if this is copper or aluminum.I don't have a chemistry lab to find out. But what it looks like under a microscope is copper wire which is tinned down its entire length. There is a copper colored core in each strand of wire with a silver colored covering. This wire is easily soldered which is indicating to me that it is tinned... This wire worked well for my use which was to drive Nema 17 stepper motors in a 3D printer.

Good

I tried using 18 gauge solid wire because I could get it locally and I realized why you don't use solid wire for led strips. The solid wire is too stiff and won't flex or bend like the stranded wire. So I have bought and continued to rebuy this wire. It flexes and solders well to the strips. Highly recommended.

I bought this for some Arduino projects I work on for Halloween, basically to connect ultrasound sensors and other devices that have 4-5 connections. I found this extremely high quality and it also looks very good for your projects with the wire colors. Thanks again!

I have 20+ spools of these all running at max length powering light-o-rama RGB 5 volt and 12 volt strings. No issues at all. Make sure to get decent power supplies. I use the Mean Well 5 volt and 12 volt PS' found here:https://www.amazon.com/gp/product/B00IWC2RLS/ref=oh_aui_search_detailpage?ie=UTF8&psc=1https://www.amazon.com/gp/product/B007K2H0GI/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

It's what the description says it is, and for something simple like this, that's what it needs to be for 5 stars. 18 AWG is a great conductor cross section for longer runs to LED strips. The spool is sturdy. The insulation is brightly colored and pulls apart easily and cleanly.

Just what I needed
