SUNVIE Fastlock2 Low Voltage Wire Connector Landscape Lighting Connectors Waterproof 12-18 Gauge Wire Connectors for Low Voltage Landscape Lights Outdoor Landscape Path Lights, 20 Pack

What It Is

The SUNVIE Fastlock2 connectors are waterproof wire splices for 12–18 gauge low-voltage landscape lighting systems. They join or repair wires in outdoor path lights, spotlights, and similar 12V or 24V landscape circuits without requiring tools or soldering.

Fitment & Compatibility

• Wire gauge: Works with solid or stranded copper wire from 12 to 18 AWG. Check your cable’s gauge—12 AWG is thicker than 18 AWG.
• Voltage: Designed for low-voltage (12V/24V) landscape lighting only. Do not use with line-voltage (120V) systems.
• Cable type: Best for direct burial or outdoor-rated low-voltage wire. Not compatible with aluminum or fine-stranded speaker wire.
• Compatibility: Universal fit for any brand of low-voltage landscape lighting (e.g., Hampton Bay, Volt, Malibu), as long as wire gauge matches. No proprietary system lock-in.

Key Things to Know

• Truly waterproof: Each connector has a silicone gel-filled cap and an inner O-ring, rated for direct burial. Tested to withstand rain, sprinklers, and ground moisture.
• Tool-free install: Push the wire in, close the lid, and snap shut. No crimping, stripping, or twisting required. Works well for quick repairs or new runs.
• Reusability: Can be reopened and reused if you need to change a fixture, but the seal degrades after a few cycles. Best for permanent installs.
• Gotcha: The snap-lock lid can be stiff on some connectors—use pliers to fully close if hand pressure isn’t enough. Also, make sure wires are fully inserted to the stop; partial insertion causes poor connection.

Should You Buy It

Buy these if you need a fast, reliable, waterproof splice for low-voltage landscape wiring and want to avoid crimp connectors or heat shrink. They’re ideal for DIYers replacing or adding path lights, but skip them if you prefer traditional crimp-and-heat-shrink methods for maximum durability.
