A practical emergency-lighting setup uses more than one light and more than one location. Keep a larger flashlight or lantern as your primary source, then use small backup lights at the places you are likely to visit first: the breaker panel, weather radio, nightstand, kitchen drawer, basement, and vehicle emergency kit. Gator Eyes are useful here because a compact light can stay beside the task instead of being borrowed for everyday use and never returned.
During a power outage, a clipped or magnet-mounted light can also keep both hands free while you check a panel, move supplies, or look through a kit. If you keep any battery-powered light for emergencies, check it periodically rather than assuming stored gear is automatically ready forever.
