4. Safety Information
Please read and understand all safety instructions before installation and use. Failure to follow these instructions may result in electric shock, fire, or other hazards.
- Low Voltage System: This fixture operates on 12-Volts. A low voltage transformer (not included) is required for installation. Do not connect directly to 120V AC power.
- Professional Installation: If you are unsure about any part of the installation process, consult a qualified electrician.
- Bulb Handling: When installing or replacing the MR16 LED bulb, avoid touching the glass with bare hands. Oils from your skin can reduce bulb life. Use a soft cloth or gloves.
- Wattage Limit: Do not exceed the maximum wattage marked on the fixture label.
- Wiring: Ensure all wire connections are secure and waterproof. Use appropriate wire nuts or connectors for outdoor use.
- Grounding: Ensure the ground stake is firmly inserted into the ground to provide stability.
- Maintenance: Disconnect power to the fixture before performing any maintenance or bulb replacement.
5. Setup and Installation
Installation requires a low voltage transformer and low voltage cable, which are not included. Follow these steps for proper installation:
5.1. Planning and Layout
- Lay Out the Lights: Determine the desired locations for your spotlights in your garden, lawn, or other outdoor areas.
- Plan Cable Route: Plan the layout for your low voltage cable (AGW cable recommended). Dig a shallow trench to lay the cable, ensuring it is protected from damage.
- Connect to Transformer: Install and connect the low voltage cable to a suitable low voltage transformer (not included).

5.2. Fixture Assembly and Wiring
- Remove Glare Guard & Shield: Unlock the screw and carefully remove the glare guard and shield from the fixture.
- Install MR16 Bulb: Insert the MR16 LED bulb into the socket. Ensure the bulb's wattage matches or is below the maximum wattage specified on the fixture label. Handle the bulb with a soft cloth to avoid touching it with bare hands.
- Install Glare Guard & Shield: Screw the shield back onto the fixture. Pass the glare guard over the shield and secure it with the lock screw. Tighten until snug.
- Install Stake: Determine the desired location for mounting the fixture. Hammer the ground stake into the ground until its flange is flush with the grade. To prevent damage, place a board on top of the stake while hammering. If the ground is hard, make a pilot hole using a flat shovel.
- Install Fixture to Stake: Thread the fixture's pigtail cable through the middle hole of the stake. Lay the luminaire pigtail into the wireway slot and screw the fixture onto the stake. Tighten until snug.
- Wire Connections: Strip both leads from the fixture's pigtail. Use the provided fastlock wire connectors to connect the leads from the fixture to the main low voltage supply cable. Ensure connections are secure and waterproof.
