What to know before buying

Listing details to confirm

The listing details conflict or remain unconfirmed: its title says the adapter fits 3-inch post light fixtures, while feature text gives a 2.5-inch top mounting surface diameter. The feature text states 5.5 "L* 5.5" W * 4 "H, whereas another dimension field gives 14L x 14W x 10.2H centimetres and the product-details field gives 13.97 x 13.97 x 10.16 cm; 839 g. It also describes a mounting adapter but includes unrelated lighting claims such as App control, solar or battery power, and waterproofing. Confirm the adapter dimensions and fixture compatibility before ordering.

Aggregate ratings are mixed: most ratings fall in the five-star category, while a notable share are one-star. With no review-summary evidence, these figures do not establish why customers rated it that way. For a mounting adapter, verify fit and dimensions directly rather than treating the overall rating as evidence of compatibility.
