What Customers Are Saying

Customers overwhelmingly praise these solar post lights for their attractive prismatic design, easy installation, and effective ambient lighting. Most highlight the soft, patterned glow that creates a warm, inviting atmosphere on decks and patios. Installation takes under ten minutes with multiple mounting brackets adapting to various post sizes. The dual-color setting—switching between cool white and warm yellow tones—is widely appreciated, with many noting excellent brightness on higher settings. A few report inconsistent performance or reduced functionality in limited sunlight, but most customers still recommend them despite minor concerns.

Looks great and easy to Install

Would Recommend

Great value. Twist off top to access the switch inside that comes in the "OFF" position. Change it to set the brightness for either a soft glow or the brighter white. Place the unit in full sun for 12 hours the first day and, if your fence post gets sunlight during the day, it will always recharge. Comes with adjustable base attachment to fit most posts and it's easy to install. Love it.

Post cap solar lights

Would Recommend

These post lights softly illuminate my deck and staircase without flooding the area with excessive light. Unfortunately they come with hard plastic pieces to allow the light to fix to various sized posts. Each light come in a plastic box with a plastic bag of screws. There is plenty of trash to contend with from the packaging.

Make sure the solar panel absorbs sufficient sunlight for 10-12 hours. Keep the solar Panel clean to ensure maximum charging performance.
