Solar powered energy efficiency Harnesses efficient solar charging to store energy during daylight and automatically emit a soft glow at night. No external power supply or battery replacements needed. Dynamic light system Built-in intelligent LED technology cycles through seven gradient hues, projecting shimmering reflections onto pools or walls. Eco-friendly luminosity for immersive atmosphere. Auto-adjusting ambient sensor Light-detection sensor provides intelligent brightness control. Illumination activates at dusk and automatically adjusts output with no manual intervention. Submersible safety Airtight sealing technology prevents water penetration during prolonged immersion. Waterproof construction ensures stable use in wet conditions. Use scenarios - Evening pool ambience: float these lights in the pool to create a soft glow and colorful reflections for family or guest gatherings. - Poolside wall accent: position near the water’s edge to project shimmering reflections onto adjacent walls during outdoor events. - Low-maintenance décor: rely on auto-on dusk illumination for seasonal or year-round lighting around the pool area without wiring.
