Installation (Setup)
Before installation, ensure your low-voltage transformer is unplugged and turned off. Plan the placement of your flood lights to achieve desired illumination.
- Prepare the Location: Choose a suitable location in your garden or landscape. Ensure the area is clear of debris and that the ground stake can be firmly inserted into the soil.
- Attach Ground Stake: Securely attach the ground stake to the bottom of the flood light fixture.
- Position the Fixture: Insert the ground stake into the desired location in the soil. Adjust the angle of the flood light to illuminate the target area (e.g., a tree, shrub, or architectural feature).
- Connect to Low-Voltage Cable:
- Locate the low-voltage main cable in your landscape lighting system.
- Open the low-voltage connector attached to the flood light's cable.
- Carefully position the main low-voltage cable within the connector, ensuring the two metal prongs pierce the insulation to make contact with the copper wires inside.
- Close the connector firmly until it locks, creating a secure and waterproof connection.
- Secure Excess Cable: Bury any excess cable or secure it discreetly to prevent tripping hazards and maintain a tidy appearance.
Operation
Once installed and connected to a compatible low-voltage transformer, the flood light will operate according to the transformer's settings. Most low-voltage transformers feature a timer or photocell for automatic dusk-to-dawn operation.
- Power On: Plug in your low-voltage transformer and turn on its power switch.
- Adjust Settings: Refer to your low-voltage transformer's manual for instructions on setting timers or photocell functions to control when your flood light turns on and off.
- Manual Control: If your transformer has a manual override, you can turn the lights on or off as needed.
Maintenance
- Cleaning: Periodically clean the glass lens and fixture body with a soft, damp cloth to remove dirt and debris. Do not use abrasive cleaners.
- Bulb Replacement:
- Disconnect power to the fixture at the transformer.
- Carefully unscrew the front housing or cover to access the bulb.
- Remove the old 20-Watt Bi-Pin halogen bulb.
- Insert a new 20-Watt Bi-Pin halogen bulb, ensuring it is seated correctly. Avoid touching the new bulb with bare hands, as oils can reduce bulb life. Use a clean cloth or gloves.
- Reattach the housing or cover, ensuring a tight, waterproof seal.
- Restore power to the transformer.
- Inspect Wiring: Annually inspect the low-voltage wiring and connectors for any signs of damage, corrosion, or loose connections. Repair or replace as necessary.
