Installation Guide
Follow these steps for proper installation of your deck lights and transformer:
1. Planning and Placement
- Choose Locations: Determine the desired locations for each deck light. Consider areas that require illumination for safety or ambiance, such as stairs, deck edges, or pathways.
- Transformer Placement: Select a suitable outdoor location for the transformer. It should be mounted vertically at least 1 foot (30cm) above ground level, protected from direct heavy rain, and within reach of a 120V AC outdoor power outlet. Ensure the photocell sensor on the transformer is not obstructed and can detect ambient light changes effectively.
- Cable Routing: Plan the routing of the low voltage cables from the transformer to each light. Ensure cables are protected and not a tripping hazard.

2. Installing the Transformer
- Mounting: Use appropriate screws (not included) to securely mount the transformer to a wall or sturdy post. Ensure it is mounted vertically with the sensor facing upwards and unobstructed.
- Power Connection: Do NOT plug the transformer into the outlet yet.

3. Installing the Deck Lights
- Drilling Holes: For recessed installation, drill appropriate sized holes (refer to product dimensions for exact size, typically around 1 inch / 25mm diameter) at each planned light location. Ensure the depth is sufficient for the light body.
- Inserting Lights: Gently push each LED deck light into its drilled hole until it sits flush with the surface. The black protecting shell can be used for embedded installation on floor/stone stairs for added safety.
- Connecting Lights: Connect the cables from each light to the main low voltage cable coming from the transformer. The lights feature durable and stable copper 2-pin connectors for easy and secure connections. Ensure all connections are tight and waterproof.

4. Final Connection
- Once all lights are connected to the low voltage cable and the transformer is mounted, plug the transformer into a grounded 120V AC outdoor power outlet.
Operating Instructions
The 65W transformer features a built-in photocell sensor and a programmable timer for automated operation.
Photocell Sensor (Dusk-to-Dawn)
- The transformer is equipped with a photocell sensor that automatically detects ambient light levels.
- When set to "Auto" mode, the lights will turn on automatically at dusk and turn off at dawn.
- Ensure the sensor is not obstructed by objects or debris for accurate light detection.

Timer Function
The transformer allows you to set a countdown timer for the lights to turn off after a specified duration from dusk.
- Mode Button: Press the "Mode" button to cycle through the operating modes: ON/OFF, Photo (Dusk-to-Dawn), and Auto (Dusk-to-Dawn with Timer).
- Time Setting: When in "Auto" mode, press the "Time" button to select the desired countdown duration: 1, 3, 5, 7, 9, or 11 hours. The corresponding indicator light will illuminate.
- Operation: If you select a timer setting (e.g., 3H), the lights will turn on at dusk and automatically turn off 3 hours later.
- Memory Function: The transformer retains your last selected timer mode even after a power outage.
