Where the points went
The Solar Score weighs performance, build, value, safety and warranty. For a fence light, safety means a stated IP code; three picks here state IP65, one states IP44, and one states water resistance without a code. Four of the five state a warranty term, from 1 year to 2 years. How we pick explains the weights.
| Product | Solar Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| Lightkeeys 8-Pack Fence Lights | 9.7 | 30 | 21 | 22 | 8 | 2 |
| Bridika Solar Fence Light | 9.6 | 29 | 20 | 21 | 8 | 2 |
| Toeuie 2-Pack Fence Lights | 9.6 | 30 | 19 | 22 | 8 | 0 |

| SIEDiNLAR 4-Mode Post Cap | 9.6 | 29 | 21 | 20 | 4 | 2 |
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 aluminum fence under 20
Pick the form for your fence
Post caps sit on post tops; wall lights screw or tape to rails and pickets. The SIEDiNLAR caps fit 4×4 to 6×6 posts, while the wall lights mount anywhere flat. For capped aluminum posts, the Egadis more pick below is made for 2.56-inch posts including aluminum.
Compare brightness in lumens
Stated figures run from 20 lumens on the SIEDiNLAR caps to 60 lumens on the Toeuie 2-pack, with the Bridika at 30 lumens. The Lightkeeys 8-pack states no lumen figure, so compare it on pack size and modes instead.
| Light | Brightness | Pack |
|---|---|---|
| Lightkeeys 8-Pack Fence Lights | Not stated | 8 |
| Bridika Solar Fence Light | 30 lumens | 1 |
| Toeuie 2-Pack Fence Lights | 60 lumens | 2 |
| SIEDiNLAR 2-Mode Post Cap | 20 lumens | 1 |
| SIEDiNLAR 4-Mode Post Cap | 20 lumens | 1 |
Check the IP code
The Bridika, Toeuie and Lightkeeys state IP65, the SIEDiNLAR 2-mode states IP44, and the 4-mode states water resistance without a code. For an exposed fence line, the IP65 picks state the stronger code. See our best solar lights for aluminum fence for the non-budget picks.
Read the warranty
The Bridika and Lightkeeys state 2 years, both SIEDiNLAR caps state 1 year with 24-hour support, and the Toeuie states none. On a budget pick, a stated term is a real differentiator.
Sizing Notes
- Match the mount to the fence: post caps for capped posts, wall lights for rails and pickets.
- For aluminum fences, check post size; the Egadis more pick fits 2.56-inch posts including aluminum.
- Compare stated lumens where given; two picks state none.
- Prefer a stated IP65 code for exposed fence lines.
- Charge in full sun; several listings state 4 to 6 hours for a full charge.
