KEILAIMO Solar Post Cap Lights – 12-Pack for 4x4/5x5 Posts | IP65 Outdoor Deck Lighting

Transform evenings with subtle, inviting light

KEILAIMO Solar Post Cap Lights come as a reliable 12-pack designed to illuminate outdoor posts with a soft, welcoming glow. They fit common wood and vinyl posts—3.5x3.5, 4x4, and 5x5—and include two extra adapter bases for a precise, one-step fit. An ultra-simple installation system means you can mount them in minutes using the screws provided, letting you quickly upgrade your deck, fence line, or garden borders.

Two lighting moods to suit every moment

Choose between a warm, sunset-inspired glow and a crisp cool white light to match the mood of the moment or the time of day. Before first use, slide the switch to your preferred mode so the lighting behavior aligns with how you want your space to feel—soft ambience for evenings or bright clarity for late-night yard tasks.

Energy-smart performance for longer evenings outdoors

Powered by upgraded solar panels, these post caps are designed for efficiency. With a typical sun exposure of 6–8 hours, the batteries are primed to deliver a steady glow for 10–12 hours from dusk to dawn. While performance will vary with weather and sun, the system is designed to maximize daylight to extend your outdoor lighting windows without wires or batteries to replace.

Durable, seamless design built to endure

Our upgraded one-piece design runs from top to base, eliminating gaps that can invite water intrusion. This integrated construction contributes to wind and rain resistance, helping maintain a clean, uninterrupted light along your posts. The lights carry an IP65 rating, delivering protection against dust and high-pressure water jets for year-round use.
