Fortify your outdoor safety with the Infinity X1 2 Pack Solar Security Lights, exclusively at Costco—these innovative lights feature a smart proximity sensor that automatically adjusts brightness in three levels: a gentle 30-lumen ambient glow for all-night visibility, stepping up to 500 lumens when motion is detected at farther distances, and delivering a powerful 2000-lumen burst when someone approaches nearby to brightly illuminate driveways, pathways, and entry points. This intelligent escalation deters potential intruders by suddenly flooding the area with intense light as they get closer, while the wireless linking allows the pair to work together for expanded coverage without any wiring hassles. Weatherproof and powered by reliable Li-ion rechargeable batteries with built-in solar panels, they install easily to provide dependable, energy-efficient protection for your home's perimeter day or night.
