The LumenstarLED LS-IW-18-2-100 is an 18 AWG, 2-conductor stranded wire specifically rated for indoor use, supplied in a convenient 100-foot (30.5 metre) roll. The stranded configuration consists of multiple fine copper filaments twisted together, which gives this wire its signature flexibility and makes it significantly easier to handle than rigid solid-core alternatives. This construction is especially valuable when navigating complex LED lighting layouts in finished spaces.
The wire features two clearly colour-coded conductors — red for positive and black for negative — allowing installers to maintain correct polarity throughout an entire circuit without second-guessing. This simple yet critical detail helps prevent wiring errors that can damage sensitive LED drivers, controllers, and fixtures. Colour coding also accelerates troubleshooting and future service calls, saving valuable time on the job.
Rated for indoor applications, this wire's insulation is engineered to meet interior installation standards, providing reliable protection against abrasion, heat, and electrical faults within walls, ceilings, and junction boxes. It is well-suited for low-voltage LED lighting systems, including under-cabinet lighting, LED strip power feeds, retrofit driver connections, and decorative fixture wiring in both residential and light commercial settings.
The 18-gauge conductor size strikes the ideal balance between current-carrying capacity and wire flexibility for most low-voltage LED applications. It handles the wiring demands of LED drivers and transformers efficiently, ensuring stable power delivery and minimizing voltage drop over reasonable run lengths. Always verify your specific amperage requirements against the wire's rated capacity to ensure a safe and compliant installation.
As part of the LumenstarLED accessories lineup, this wire is designed to integrate naturally with other LumenstarLED products and compatible LED systems. The full 100-foot roll is an economical and practical choice for contractors and installers who work on multiple projects, providing enough wire to complete several runs from a single purchase. Keep a roll on hand and simplify your LED lighting wiring workflow from start to finish.
