40 ft 18 AWG four conductor RGB LED extension wire on spool

TAURKENAM

TAURKENAM 40FT 18AWG 4pin RGB LED extension wire power adapter

SKU CH-S9B3-29VHG

A 40 ft 18 AWG four-pin cable extends RGB LED strips rated for 300 V and 3.5–4 A from −20 °C to 80 °C

  • 40 ft length extends RGB strips across large rooms
  • 18 AWG oxygen-free copper handles up to 4 A with low loss
  • 300 V rating supports standard LED power supplies
  • Four conductors match SMD 5050 and 3528 RGB pinouts
  • Flexible jacket bends easily and works from -20 to 80 °C

40FT 18AWG 4-pin RGB LED extension

This 40FT 18AWG 4-pin RGB LED extension wire suits installers and hobbyists extending SMD 5050 or 3528 strip lighting runs. High-purity oxygen-free copper with tin plating keeps resistance low while the flexible jacket bends arbitrarily for tight routing around cabinets, coves or signage.

Sustained-load current and temperature limits

The cable is rated for a maximum continuous current of 3.5A-4A at up to 300V and an operating range from -20 to 80. Under steady load the conductors stay within spec without the voltage drop seen in thinner hookup wire, making it reliable for transformer feeds, splitter chains or motor leads that run for hours.

300V insulation ceiling and four-conductor layout

The 300V insulation ceiling defines the practical ceiling for low-voltage LED systems; exceeding it risks breakdown even if the strips themselves draw little power. Only four conductors are provided, so single-colour, dual-white or addressable strips needing five or more wires cannot use this cable without a separate return path.

Questions about this item

Does the 18AWG wire run hot when carrying 3.5A continuously?

The cable is rated for up to 3.5–4A at 300V and uses oxygen-free copper with tin plating for low resistance, so it stays within safe temperature limits at full load.

What connectors or controllers must I already have to use this 4-pin RGB extension?

You need a compatible 4-pin RGB header or controller that matches the 4-color pinout used by SMD 5050 or 3528 strips.

Can I join this 40ft spool to an existing 5050 LED strip without soldering?

Yes, cut the wire to length, strip the insulation with a wire stripper, and connect the exposed conductors to the strip’s 4-pin pads or terminals.
