## Before you buy

- The listing gives several post-fit claims, including standard 4x4 wood posts with an actual size of 3.5x3.5 inches and 4x4 or 5x5 vinyl caps. Customer feedback reports both good fits and posts the lights did not fit, so compare actual cap dimensions and mounting bases before ordering. The claimed over-10-hour runtime depends on 4–6 hours of direct sunlight.

## In the box

- 12 solar post cap lights (Check selected pack): The product title and pack details specify 12 lights.
- Mounting hardware (Included)

## A good fit for

- Buyers wanting a matching set of solar cap lights for outdoor fence or deck posts.
- People seeking cool-white accent lighting without wiring, with sunlight available for charging.

## Less suited to

- Buyers who need bright area or task lighting rather than low-output post accents.
- Buyers unable to confirm that the fixture bases fit their specific post caps.

## Customer feedback

Customer feedback is generally favorable about quality, appearance, brightness, installation, reliability, and lighting through the night. Those impressions suit the listed solar post-light role, although the stated output is only 20 lumens per light and does not indicate strong area lighting. Fit is a meaningful mixed point: some customers report a good match while others say the lights did not fit their posts, so measure before choosing.
- Positive themes: Customers praise the appearance, ease of installation, and reported overnight operation.
- Mixed feedback: Fit feedback is mixed, with reports of both suitable matches and posts the fixtures would not fit.
