SUNVIE Fastlock2 Low Voltage Wire Connector Landscape Lighting Connectors 14-18 Gauge Waterproof Low Voltage Connectors Outdoor Landscape Wire Connector for Garden Yard Path Lights, 24 Pack

Sunvie products are the best. These connectors are so easy to use. I have never had problems with my lights.

Awesome gadgets! I can’t say how many hours of work these saved me. I had to wire 23 led outdoor lights (that I converted from solar to regular power). Just ran the cable all along muy fence and then clipped these connectors.

Product as described and works great! Would recommend and purchase again! Appears to be well built, easy to use, and great value for the money spent.

They work really well but are a bit or a pain to install. The pins aren't really sharp enough to poke through the insulation easily and the compression fittings won't take solid wire or anything larger than 14g. Those are both minor and can be overcome by tightening the posts well. The resulting connections were 100% good and seem reliable. You NEED to use tools (wrench, socket, etc) to tighten the posts. If you try and do it by hand, you'll rip up the skin on your fingers!

Product description says it works with 12 gauge wire. Technically, the wire fits in the slots, but I strongly recommend NOT using these for 12 gauge. I very carefully and, as tightly as I could, used these. More than half of my lights didn’t have a connection. I tried multiple times and sometimes they’d work and sometimes not. I just think the wire is too thick to ensure a good, solid connection. I can’t even really tighten the plastic nuts enough to stay threaded. Finally I threw them away and used the wire nuts that came with the lights and every problem was solved. This isn’t rocket science. There connectors are quick and easy, but I’m guessing only for thinner wire.

Great product this was an addition to existing lights

These connectors were perfect for the installation of our low voltage backyard lighting. I just completed the installation this week and it made everything so much simpler and quicker. Time will tell if they hold up in the outdoor wet conditions next winter, but for now I am a happy camper. I read another review that someone complained that the 12 & 14 gauge wire didn't fit for them, but I used 14 gauge for the closer runs and 12 gauge for the 100 ft run. All 17 of the lights are functioning well. There were no issues inserting the wires into this connector. Not sure what their issue was. I didn't have that problem. One connection came without two of the 4 caps, but I ordered extra. Not a problem. The only challenge I had was in splitting the two halves of the wire. On 3 of the 17 I did manage to slightly expose the wire on one side. I used electrical tape and sealed it up. Lights work. I am happy. I would absolutely recommend these electrical connections.

The SUNVIE Fastlock2 wire connectors are convenient for quick landscape lighting installs, especially with standard 12–16 gauge wire. The waterproof design and snap-lock mechanism make setup fast, and they hold up well in outdoor conditions. However, when working with thicker gauge wire (like 10 or 12 stranded), the experience becomes frustrating. The connectors feel tight and unforgiving, often requiring excessive force to close—and even then, the connection isn’t always reliable. In some cases, I had to resort to traditional wire nuts just to get a secure fit. For basic garden lighting with thinner wire, these are fine and functional. But if you're running heavier gauge for longer distances or higher loads, you may want to look elsewhere. Average performance overall, with limitations that show up quickly in more demanding setups.
