Where the points went
The Solar Score weighs performance, build, value, safety and warranty. For a deck railing light, safety means the ingress protection the listing states; a listing that states no IP number scores zero on that line. Only one of the five states a warranty term. How we pick explains the weights.
| Product | Solar Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| VOLISUN 12 Pack Post Cap | 9.6 | 28 | 21 | 21 | 7 | 3 |
| Melunar 6 Pack Dual Mode | 9.6 | 30 | 21 | 21 | 5 | 0 |

| PATIOWIN 12 Pack | 9.4 | 27 | 20 | 20 | 0 | 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 deck railing

The VOLISUN is a post cap for 4×4 wooden posts (actual 3.5 by 3.5 inches) and 4×4 vinyl posts (actual 4 by 4 inches), with two bases in each package. The other four are step lights that screw or glue onto flat surfaces like rails, fences and stairs. See our solar path and string lights category for more ways to light a yard.
| Light | Brightness | Run time | Ingress protection |
|---|---|---|---|
| VOLISUN 12 Pack Post Cap | Not stated | 10-12 hours | IP64 |

| SOLPEX 16 Pack | 200 lumens | Not stated | IP44 |
| Melunar 12 Pack Warm White | 5 lumens | 8-12 hours | IP44 |

The VOLISUN states no brightness figure. Read the stated numbers side by side rather than across brands, since each lists what it lists. The stated figures guide the choice. figures.
Read the run time and charge lines
The VOLISUN states 10 to 12 hours of night run time after 6 to 8 hours of charge, the Melunar 12-pack states 8 to 12 hours after 4 to 6 hours of charge, and the Melunar 6-pack states 8 hours after 4 to 5 hours of charge.

Check the warranty and service lines
The VOLISUN is the only one here with a stated service term: a full 2-year service covering defects. The other four state no warranty term. For lights that live outside year-round, the stated service line is the tie-breaker.

- Compare brightness as stated: 200 lumens, 10 lumens per lamp, 5 lumens, or 3 lumens.

- Read the ingress rating each listing states: IP64, IP55, IP44, or none.
