Who should buy it (and who should skip it)
A good match for homeowners with 4x4 fence or deck posts who want low-effort accent lighting that needs no wiring. The adjustable color and brightness help set the mood. Skip it if your posts are a different size, you need a very bright security light, or your posts sit in deep shade.
Before you buy the ROMANJOY 4×4 Solar Post Cap Lights Waterproof: quick tips
- Measure your posts; the seller lists a 4.06 inch inner base for standard 4x4 posts.
- Place them where the panel gets direct sun, and wipe the panel clean now and then.
- Avoid spots with strong night lighting, because the light sensor may stay off or cycle.
- Check color options; the listing offers three variations, so pick the right pack size and finish.
