Where the points went
The Solar Score weighs performance, build, value, safety and warranty. For a wrought iron fence light, safety means a stated IP weather rating and the protections the listing actually names; a light that states no IP rating scores low on that line, whatever its looks. Two of the four listings state a concrete warranty term: 2 years and 1 year. How we pick explains the weights.
| Product | Solar Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| PARTPHONER 12-Pack Post Cap | 9.7 | 29 | 21 | 21 | 7 | 4 |
| Lunilly 4-Pack Post Cap | 9.5 | 27 | 20 | 20 | 5 | 3 |
| Yesprumlves 12-Pack Post Cap | 9.5 | 28 | 20 | 20 | 7 | 0 |
| Tujoe 16-Pack Post Cap | 9.5 | 28 | 20 | 21 | 5 | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.
How to choose the best solar lights for wrought iron fence
Match the cap to the post
Three picks here are made for 2×2 inch metal posts. The Lunilly is designed for 2-inch square aluminum or metal fence posts with a pop-on design, and the Tujoe and Yesprumlves both name 2×2 inch metal fence posts, with the Yesprumlves including mounting rings. The PARTPHONER is the odd one out: it fits 4×4 wood and vinyl posts, not iron. Measure the actual post before ordering. See our path, string and deck light guides for more outdoor lighting.
Decide how much color you want
Two picks do more than white light. The PARTPHONER offers 9 fixed colors plus 2 dynamic modes with a memory feature, and the Lunilly offers warm white, cool white, RGB and a color-changing holiday mode. The Tujoe and Yesprumlves are white light only. For a fence that hosts parties, the color picks earn their keep; for a quiet boundary, white is enough.
| Light | Post fit | Weather rating |
|---|---|---|
| PARTPHONER 12-Pack Post Cap | 4×4 wood/vinyl | IP54 stated |
| Lunilly 4-Pack Post Cap | 2×2 metal | Not stated |
| Yesprumlves 12-Pack Post Cap | 2×2 metal | IP44 stated |
| Tujoe 16-Pack Post Cap | 2×2 metal | Not stated |
Read the weather rating
Iron fences live outside all year, so the IP number matters. The PARTPHONER states IP54 and the Yesprumlves states IP44. The Lunilly claims weather resistance with no IP number, and the Tujoe claims water and wind resistance with no IP number either. For a fence that faces rain and snow for years, a stated IP number says more than any adjective. Our best solar lights for metal fence roundup covers more metal-friendly options.
Check the runtime against the night
The Lunilly states up to 12 hours on a full charge, the PARTPHONER states 8 to 9 hours from 4 to 6 hours of sun, and the Tujoe states up to 8 hours. The Yesprumlves states its battery covers a bright all night. Every listing ties runtime to sun hours, so keep the cap tops clear of leaves.
Mind what is missing
Listings differ in what they leave out. The Tujoe title and bullets say 16 pieces while the included components list 6 fence post lights; trust the 16. The PARTPHONER title claims 3 modes while the bullets describe 9 colors plus 2 dynamic modes. The Yesprumlves warranty description reads only “1” with no unit, so no concrete term is stated. When a listing does not state something, the review says so rather than guessing.
Sizing Notes
- Match the cap to the post: 2×2 inch metal posts are the size three listings name.
- Compare stated brightness against what you need: 20 lm to 150 lm here, with one listing stating none.
- Check the stated weather rating against your climate: IP54, IP44, or none stated.
- Use the charging hours the listing states: 6 to 8 hours of sun for the runtimes claimed.
