I recently installed a WILAWELS D11LT06 transformer and connected it to twelve 6W 700LM lights over approximately 60 feet using 12-gauge wire. Only the first two lights fully illuminate, the next two are dim, and the rest do not turn on. Should I have used a different wire gauge?

Based on your setup, 12-gauge wire is generally sufficient for a 60-foot run with a 72W total load (12 lights x 6W). However, the symptoms you are describing—where lights get progressively dimmer and then fail—are classic signs of voltage drop or a poor connection along the line.To resolve this with your WILAWELS D11LT06 transformer, try the following steps:Switch to the 14V Terminal: The D11LT06 features dual output terminals (12V and 14V). If your lights are currently connected to the 12V terminal, move the wire to the 14V terminal. This higher voltage is specifically designed to compensate for voltage drop over longer cable runs.Check Connections: Since the failure starts after the second light, inspect the connection between the second and third light, and the third and fourth. A loose or corroded connector at the third light could be preventing adequate current from reaching the rest of the chain.Verify Total Wattage: Your total load is 72W, which is well within the 200W limit of the D11LT06. Since you are not overloading the transformer, the issue is almost certainly in the distribution (wiring/connectors).Check for Shorts: Ensure that no copper strands are touching between the positive and negative lines at any of the light tap-ins, as this can cause partial power loss without necessarily tripping the circuit breaker immediately.If moving to the 14V terminal and tightening connections does not fix the issue, there may be a break in the wire or a defective fixture at the point where the lights stop illuminating.

5. Setup and Installation

5.1 Mounting the Transformer

Choose a suitable outdoor location for wall mounting. The location should be protected from direct heavy rain and easily accessible.
Ensure the mounting surface is sturdy enough to support the transformer's weight.
Use appropriate screws and anchors (not included) to securely mount the transformer to the wall.

5.2 Connecting Low-Voltage Wiring

The transformer features dual terminal outputs (12V and 14V) to accommodate different lighting needs and cable lengths.

Turn off the main power supply before making any connections.
Strip approximately 1/2 inch of insulation from the ends of your low-voltage landscape lighting cables.
Loosen the terminal screws on the transformer's output block.
Insert the bare wire ends into the desired 12V or 14V terminals. Ensure a secure connection by tightening the screws.
Connect your landscape lights to the low-voltage cables according to their individual instructions.

5.3 Connecting the Photocell Sensor

The detachable photocell sensor allows for automatic dusk-to-dawn operation.

Plug the photocell sensor's connector into the designated port on the transformer.
Position the photocell sensor in a location that receives natural ambient light, free from obstruction or artificial light sources (e.g., porch lights) that could interfere with its operation.

8. Troubleshooting

If you encounter issues with your transformer, refer to the following troubleshooting guide:

Problem	Possible Cause	Solution
Lights do not turn on.	No power to transformer, circuit breaker tripped, incorrect mode selected, faulty wiring, photocell obstructed.	Check power outlet. Reset circuit breaker. Verify mode setting. Inspect low-voltage wiring for breaks or loose connections. Ensure photocell is clear and receiving light.
Lights stay on continuously.	ON mode selected, photocell not functioning or receiving too much light.	Change to desired automatic mode. Relocate photocell to a darker area or ensure it's not covered.
Lights turn on/off at incorrect times.	Incorrect clock setting, photocell interference, incorrect mode programming.	Adjust the clock. Ensure photocell is not affected by artificial light. Re-program the selected mode (Timer, Countdown, Dusk On Timer Off).
Circuit breaker trips repeatedly.	Overload (too many lights), short circuit in wiring or lights.	Reduce the total wattage of connected lights. Inspect all low-voltage wiring and light fixtures for short circuits. Disconnect lights one by one to identify the faulty component. Reset the circuit breaker after troubleshooting.
