SUNVIE Fastlock2 is our pick for adding individual fixtures to a compatible low-voltage cable. Its screw-together design makes low voltage landscape light connectors easier to fit without cutting the main run, provided the cable and fixture leads match the specified gauges.

A connector has to fit both the conductor size and the task. A fixture tap is different from a splice that joins exposed ends. Before ordering, read the markings on the cable and check the manufacturer's permitted combination of wire sizes and number of conductors, not just the broad gauge range on the package. Disconnect the transformer and verify the circuit is off before touching the wiring.
SUNVIE Fastlock2: a fixture tap
SUNVIE Fastlock2 connector, 8 pack
SUNVIE earns its badge for a common job: attaching a light to an existing low-voltage landscape cable. The eight-pack supplies one connector for each of eight fixtures, and the three-piece screw design avoids cutting or splicing the main cable. The listing specifies 12, 14, 16 and 18 AWG main cable and fixture leads from 16 to 22 AWG. A nylon and fiberglass body and nickel-plated brass pins are intended for outdoor use. Pick it when the cable matches those sizes and you are adding lights along a run. It is less suitable for joining two severed cable ends: use a splice rated for the actual conductors instead. The screw assembly still needs careful seating and a secure connection.
Pros
- One connector attaches each fixture without cutting the main cable
- Accepts listed 12 to 18 AWG main cable and 16 to 22 AWG fixture leads
- Nylon and fiberglass housing surrounds nickel-plated brass pins
Cons
- Eight connectors cover only eight individual fixtures
- A fixture tap does not replace a splice for severed cable ends
GWHOLE 3-way: branch smaller conductors
GWHOLE 3-way wire connector, 20 pack
GWHOLE suits repairs or branches where the individual conductors fit its 22 to 14 AWG range. Each of the 20 gel-filled connectors accepts two or three wires, and its insulation-displacement design means the ends do not need stripping before insertion. Push each conductor fully into the connector and compress the blue cap with a crimping tool. That combination earns the small-wire badge: it gives a buyer more joining positions than a simple two-ended repair while keeping the connection compact. The tradeoff is that it is not a screw-on fixture tap, and a crimping tool is needed. A 12 AWG landscape trunk falls outside the stated wire range, so do not force one into it.
Pros
- Each gel-filled connector accepts two or three conductors
- Insulation-displacement contact avoids stripping compatible wires
- Twenty pieces provide spares for several small-wire repairs
Cons
- A crimping tool is required to compress the blue cap
- The stated 22 to 14 AWG range excludes 12 AWG cable
Dicio: twist a larger splice
Dicio waterproof wire nut, 5 pack
Dicio is the thicker-wire option in this comparison, with the listing specifying a 20 to 8 AWG range and five wire nuts in the pack. Its twist-on form joins prepared wire ends rather than piercing a continuous cable, and the manufacturer describes silicone sealant inside the connector to resist moisture. It is a sensible choice for a compatible outdoor splice when the conductors are too large for the GWHOLE connector. Strip the ends and follow the specific instructions for the permitted combination and installation. Its small pack is convenient for a limited repair but leaves fewer spares for a long installation. Do not treat the overall gauge range as permission to combine any number of large conductors in one nut.
Pros
- The stated 20 to 8 AWG range includes thicker individual conductors
- Silicone sealant inside the twist-on nut helps protect the splice from moisture
- Five-piece pack suits a small number of compatible repairs
Cons
- Wire ends must be prepared before the twist-on connection
- Only five nuts are supplied for a larger project
Match the connector to the job
Start by identifying whether you are adding a fixture to an intact main line or joining separate ends. SUNVIE is designed for the first task; the other two join conductors. Each wire in a two-conductor lighting cable needs its own correct electrical connection when a splice is required. Follow the product instructions and local electrical requirements, and use only connectors intended for the location and conditions.
A claimed gauge range alone does not tell you that every mixture of conductors fits. Check the approved wire combinations, whether the wires are solid or stranded, and the installation instructions for the exact connector. Keep joints accessible for inspection where required. If the cable marking is unreadable or you are unsure about the circuit, seek a qualified electrician's help rather than guessing.
Count the separate connections before ordering. The SUNVIE pack is intended for eight lights, whereas the other packs contain individual connectors for conductors. A cable repair may require more than one connector, so check both the quantity and any tool needed for each joint. On the AWG scale a lower number denotes a thicker conductor: 12 AWG is thicker than 14 AWG and is outside GWHOLE's stated range. Rely on the cable marking and the maker's instructions rather than judging by eye.
Frequently asked questions
Can these connectors be used on household mains wiring?
This guide concerns the low-voltage side of a landscape lighting transformer. Some connectors may list higher voltage ratings, but a rating alone does not establish that a specific installation is permitted. Follow the connector's instructions and applicable electrical rules. For mains wiring or an uncertain outdoor installation, consult a qualified electrician.
Do I need to strip the wires?
It depends on the design. GWHOLE uses an insulation-displacement contact and calls for fully inserting the unstripped wires before crimping. Dicio is a twist-on nut for prepared ends, so follow its stripping instructions. SUNVIE's screw assembly attaches a fixture to an intact compatible main cable without cutting that cable.
Which connector is right for 12 AWG landscape cable?
SUNVIE lists 12 AWG among its compatible main cable sizes and can attach a fixture with a compatible lead. Dicio lists a range that includes 12 AWG, but the exact combination of wires must also be permitted. GWHOLE's stated range ends at 14 AWG, so it is not the choice for a 12 AWG conductor.
