The 4-sentence answer
King Low-Voltage Wire (250' Roll) is a 250-ft roll of low-voltage cut-and-splice wire designed for power injection on King Permanent Lighting runs. Use to extend run distance when the standard PSU-to-string distance exceeds the in-built supply lead. Cut to length, splice with the King 3-wire waterproof connectors. Compatible with All King Permanent Lighting 24V & 36V Systems. Use only with the King Permanent Lighting ecosystem — proprietary connectors and controller communication mean cross-brand mixing is not supported.
Why the King Low-Voltage Wire (250' Roll) earns its place on the install
The backbone of any proper power injection setup. King Permanent Lighting Low Voltage Wire is purpose-built for cut-and-splice power injection applications — connecting your controller power supply or external power source to a Power Injection T Cable to maintain brightness and performance on longer runs.
Sold in 250' rolls and available in three wire sizes to match your system voltage and run distance.
- 16/2 — Suitable for shorter power injection runs
- 14/2 — Recommended for longer distances on 24V setups
- 12/2 — Recommended to handle the increased load and maintain system performance
When in doubt, go heavier gauge. Proper wire sizing is one of the most important steps in preventing voltage drop and maintaining consistent brightness across the full run.
- Designed for use with King Permanent Lighting Power Injection T Cables (cut-and-splice application)
- Compatible with blue connectors or other approved waterproof electrical connectors
- Built for low-voltage exterior applications and long-term outdoor performance
⚠️ This product requires proper cutting, splicing, and waterproof connections. It is intended for installers with experience in low-voltage wiring practices. If you are unfamiliar with cut-and-splice applications, consult a qualified installer before proceeding.

Where this part fits in the system
Long-run power injection
When the LED string run length exceeds the PSU's built-in supply lead distance, splice in additional low-voltage wire to bring the PSU power closer to the string.
Multi-PSU system installs
Large commercial properties with multiple PSUs feeding separate eave sections. Low-voltage wire runs from each PSU to its string segment.
Hidden routing under eave / soffit
When the wire path needs to be hidden architecturally, the 250-ft roll provides the slack to route around dormers, gutters, and downspouts without being seen from the street.
What this part works with
- Voltage system
- All King Permanent Lighting 24V & 36V Systems
- Controller
- King Permanent Lighting controller (24V or 36V matching variant)
- Mounting
- Inside the King Permanent rated outdoor enclosure box for code-compliant install. Power supply units must be enclosure-mounted.
- Will NOT work with
- Non-King-Permanent LED strings, controllers, or accessories. The system uses proprietary connectors and controller protocol — cross-brand mixing is not supported.

How to install King Low-Voltage Wire (250' Roll)
- Plan the system layout. King Permanent Lighting installs follow a layout-first pattern. Sketch the eave line, PSU location, controller location, and accessory placement before any wire pulls.
- Mount in the rated enclosure. PSU and controller units mount inside the King Permanent outdoor enclosure box for code-compliant install. GFCI outlet required for the supply.
- Route low-voltage wire through protective loom. Use the King Permanent protective loom along the run. Bury or tuck behind soffit where the wire isn't architecturally visible.
- Connect with King proprietary connectors. Don't splice with generic wire nuts. Use the King 3-wire connectors at every junction.
- Commission via the King controller app. Pair the controller via Bluetooth + Wi-Fi. Run a full color cycle to confirm every LED is firing before final mount.
Build quality + materials
- Outdoor-rated construction — designed for year-round outdoor exposure when mounted in the rated King Permanent enclosure box.
- Proprietary connector system — gas-tight connections that survive freeze-thaw and humidity exposure for the life of the install.
- Multi-year permanent install rated — unlike seasonal Christmas lighting, the King Permanent system is designed to stay on the eave year-round.
Warranty
1-year manufacturer warranty on King Permanent Lighting components from Christmas Lights HQ. Not covered: install outside the rated King Permanent enclosure box, cross-brand mixing with non-King components, damage from over-voltage or over-current beyond the rated spec, animal damage.
Questions contractors actually ask
Available Wire Sizes 16/2 14/2 12/2 Choosing the Right Wire Size
Getting the right gauge for your system is critical. Undersized wire leads to voltage drop, dim lights, and poor performance — especially on longer runs.
