5. Setup & Installation
Follow these steps to properly set up and install your Mlambert Solar Post Lights:
Important Notes:
- These lights are designed to fit actual post sizes: 3.5''x3.5'', 4''x4'', and 5.5''x5.5''.
- Ensure the solar panel is placed in an area that receives 6-8 hours of direct sunlight daily for optimal performance.
Installation Steps:
- Unpack: Carefully remove all solar post lights and accessories from the packaging.
- Activate: Locate the internal ON/OFF switch, usually found near the solar panel or on the underside of the light. Switch it to the 'ON' position.
- Choose Base Adapter: The lights come with different base adapters to fit various post sizes. Select the adapter that best matches your post dimensions (e.g., for 3.5x3.5 wooden posts, 4x4 vinyl posts, or 5.5x5.5 wooden posts).
- Mount the Light: There are two primary ways to fix the light base to your post:
- Method 1 (Side Fix): If the light base fully covers the top of your post, you can secure it by screwing through the side of the base into the post using the provided mounting screws.
- Method 2 (Top Fix): If the light base does not fully cover the post, or for easier installation, fix the base from above by screwing directly into the top of the post. This is often the easiest way to install regardless of post size.
- Position: Place the assembled solar post light firmly on top of your chosen post, ensuring stability.

- Daytime: The integrated solar panel will absorb sunlight and convert it into electrical energy, charging the internal battery.
- Nighttime: As dusk falls, the lights will automatically turn on, providing warm white illumination for 8-12+ hours.
- Manual Control: You can manually turn off the lights at any time using the internal switch if continuous operation is not desired.

7. Maintenance
To ensure the longevity and optimal performance of your solar post lights, follow these simple maintenance tips:
- Clean Solar Panel: Periodically wipe the solar panel with a soft, damp cloth to remove dust, dirt, or any white covering that may accumulate. A clean panel ensures efficient charging.
- Clear Obstructions: Ensure no leaves, branches, or other debris cover the solar panel, as this will hinder charging.
- Inspect for Damage: Regularly check the lights for any physical damage or loose components.
8. Troubleshooting
If you encounter any issues with your Mlambert Solar Post Lights, refer to the following troubleshooting guide:
- Light Not Turning On:
- Verify the internal ON/OFF switch is in the 'ON' position.
- Ensure the solar panel receives 6-8 hours of direct sunlight daily. Relocate if necessary.
- Check for any obstructions (e.g., leaves, dirt) on the solar panel and clean it.
- Dim Light or Short Illumination Time:
- Ensure the solar panel is clean and free from any covering.
- Confirm the lights are receiving adequate direct sunlight for charging. Shady locations will reduce performance.
- The internal battery may be reaching the end of its lifespan and might need replacement (if applicable, refer to manufacturer for battery type).
