Light up your deck, fence, or mailbox post with Home Zone Living Secure Solar Post Cap Lights. This 4-pack of solar-powered LED caps delivers ambient outdoor lighting with no wiring and no ongoing energy costs, thanks to a simple twist-on installation that fits any post under 6 inches. Switch between 3000K warm white for a cozy glow or 5000K cool white for crisp, modern illumination. The solar panel charges by day, and the light automatically turns on at dusk for up to 8 hours of nighttime illumination. A rechargeable lithium battery delivers long-lasting performance and is user-replaceable when it eventually expires. Durable, weather-resistant plastic construction holds up year-round on fences, deck railings, mailboxes, and gate posts. Each cap measures 6.18" × 6.18" × 3.62", delivers 20 lumens, and runs on a 3.2V 14500 500mAh lithium battery (LiFePO4). Includes 4 caps, 4 lenses, 4 mounts, 16 screws, 16 anchors, and an instruction manual.
