18 Gauge 2 Conductor Silicone Wire Red Black - Flexible 100ft Spool

Our review of this 18 AWG 2 conductor silicone wire finds it best suited to hobbyists, installers and DIYers who need a highly flexible, heat resistant hookup wire for single color LED strips and general DC projects. The single biggest reason to buy is its construction: each conductor is made from 150 fine stranded tinned copper strands covered in silicone rubber, which delivers notable flexibility and reliable conductivity while tolerating temperatures up to 200 deg C. For anyone wiring LED runs, model vehicles or small appliances this spool is a practical, easy to handle choice.

Key Features

• Ultra flexible silicone jacket: The soft silicone insulation keeps the cable pliable and easy to route in tight spaces without kinking.
• High strand count conductors: Each conductor uses 150 fine tinned copper strands, which improves solderability and reduces resistance for cleaner power delivery.
• Wide temperature range: Rated to 200 deg C and usable down to -60 deg C, it handles both high heat and extreme cold applications.
• 600 volt rated: The 600 V rating makes it suitable for a variety of low voltage DC electrical hookups with a safety margin.
• 100 ft spool: A full 100 ft length provides plenty of cable for medium sized projects without frequent joins.
• Color coded parallel pair: Red and black conductors are bonded side-by-side for quick polarity identification and neat runs.

Who It's For

This wire is aimed at makers, electricians doing small DC runs, and anyone installing single color LED strip lights who values ease of routing and soldering. The high strand count and tinned copper core make it ideal for repetitive bending and small form factor assemblies like model planes, cars and ships.

Those who need thick power mains cable, high current automotive battery cable, or insulated wire with an extremely tough outer jacket for heavy abrasion should look elsewhere; the silicone insulation is soft and flexible, which is a plus for routing but not a replacement for heavy duty jacketing in harsh mechanical environments.

Pros & Cons

Pros

• Excellent flexibility makes installation and routing around corners or tight housings straightforward.
• Tinned, high strand count copper offers good solderability and lower resistance that reduces heat under load.
• Wide temperature tolerance and 600 V rating increase application versatility from cold storage to heated enclosures.
• 100 ft spool is roomy enough for most moderate projects without cutting joins.

Cons

• Soft silicone jacket can be prone to nicking or tearing if abraded by sharp edges, so care is needed during installation.

Our Verdict

For LED installers, hobbyists and small equipment builders the 18 AWG red black silicone wire is a sensible, cost effective choice: it combines flexible silicone insulation, high strand tinned copper conductors and a useful temperature range that make routing and soldering easier while minimizing heat build up. It is good value for projects that need pliable, durable hookup wire, but installers should protect the jacket from sharp edges during installation.

Frequently Asked Questions

Is this cable easy to solder?
Yes, the tinned copper and high strand count make solder joints straightforward and reliable.

Can I use this for outdoor LED runs?
It can be used outdoors when protected from UV and abrasion, but the soft silicone jacket is not a substitute for conduit or additional mechanical protection.

Does the jacket withstand high heat?
Yes, the silicone insulation is rated to 200 deg C and will perform well in high temperature locations within that limit.
