Solar post cap lights sit on top of fence, deck, and porch posts and throw a 360-degree glow so the post tops themselves are the light source. Each cap is a plastic solar fixture with 8 warm white SMD LEDs — decorative outdoor lighting with no electricity required. Bases in the box are meant for wood, vinyl, and plastic posts, including the 4x4, 5x5, and 6x6 sizes in the listing. Choose Black or White, then a 2 Pack, 4 Pack, 6 Pack, or 8 Pack. See other outdoor lighting in the lights collection, and light the ground route with solar garden pathway lights if you also need a walkway edge.
What are solar post cap lights?
They are modern post cap lights that drop onto the top of a post rather than staking into a lawn. Measurement is 5.8 x 5.8 x 3.54 inches. Light brightness is 15 lumens, which the listing describes as 3× brighter than general solar garden lights. The glow is a warm white ring around the post, not a spotlight beam. For a directional 600-lumen wash on a tree or flag, use solar spot lights instead.
Use them to decorate a fence line, deck rail posts, porch posts, or a yard boundary. Because the viewing angle is 360 degrees, neighbors on both sides of a fence see the cap, not only the inside of the yard.
Which fence posts do these cap lights fit?
These fence post solar lights come with different sizes of bases, compatible with any standard true size 3.5"×3.5", 4"×4", 4.5"×4.5", 5"×5", and 5.5"×5.5" wood, vinyl, or plastic post cap. The product is sold for 4x4, 5x5, and 6x6 vinyl and wooden posts — 6x6 nominal posts are commonly 5.5" actual, which matches the largest base.
Measure the true top of the post, not only the nominal size on a lumber tag. A vinyl 4x4 and a wood 4x4 are not always the same outside dimension; that is why several bases ship with the lights. If a post already has a decorative finial you want to keep, these replace that cap rather than stacking on top of it.
How do solar post cap lights charge?
They are powered by solar and charge in full and direct sunlight for 6–8 hours. There is no household wiring. Set the caps on posts that see the sky. A post under a dense tree or a covered porch will not charge the way a fence line in the open will.
After a full charge, the 8 warm white SMD LEDs come on when the light level drops. Wipe dirt off the top after storms; a dusty cap charges slowly. Runtime follows that day’s sun, as with any solar fixture.
Which color and pack should I choose?
Color options are Black and White. Match the cap to the post or contrast it: black on dark wood or black vinyl, white on white vinyl or painted porch posts.
Size options:
-
2 Pack — a pair of gate posts or the two posts at a deck stair
-
4 Pack — a short fence run or the corners of a small deck
-
6 Pack — a typical fence section or mixed deck and porch posts
-
8 Pack — a longer fence line or a full deck perimeter
Count the post tops you actually want to light, then pick the pack. Black and White are separate options, so an order that mixes colors is two selections.
Are solar post cap lights waterproof?
The waterproof rating is IP44, suitable for outdoor use in rain, snow, frost, or sleet. That is weather protection for a post top, not a claim they belong in a fountain. Keep the solar face clear of standing water and piled snow when you can.
