Bright enough to see where you're going in the dark without turning on other lights, but not so bright as to blind you Built-in smart light sensor, the nightlight automatically lights up only when the room is dark enough Offset plugs and compact size, the nightlight does not block the second outlet Costs you less than $0.20 per year to operate (based on 11 cents/kWh), and no bulbs to replace with long life LEDs Perfect for hallway, kitchen, stairs, living room, bathroom, bedroom, nursery, anywhere you need a guiding light.
