Datexx Sentina Rechargeable Motion Sensor Light. An emergency light that never leaves you in the dark! The Sentina rechargeable LED light truly shines in emergency situations, without the hazards of candles or the limited reliability of flashlights. But even when there"s no emergency, you"ll be glad to have it. Because it"s actually FOUR lights in one! A power failure light - Plugged into any wall outlet until you need it, Sentina goes on when the power goes off... providing 8 full hours of powerful illumination. An emergency flashlight - Since Sentina is a flashlight too, you can simply unplug it and take it anywhere you need a strong, lasting light. A photoelectric night light - Switch it to photoelectric mode, and Sentina is a handy dusk-to-dawn night light that can instantly become a life-saver when needed. A motion detector light - Set on motion detector mode, Sentina will detect nearby movement and turn itself on. This is especially handy when entering a room or around a dark stairwell! The light can be set for 1 minute or 10 minutes. Use it to guard against prowlers, or to guide night-time wanderers. Size is 2.25"L x 1"W x 4"H
