The Original GuideLight includes a light sensor that turns the LEDs On/Off automatically. It is designed to increase or decrease slowly depending on the amount of light in the room. They should be at full brightness when the room is completely dark and slowly dim as the room gets lighter.
The GuideLight costs around 10 cents a year to power (depending on your local cost of power).
This LED night light has the light built into its slim and sleek design. You can have the benefit of a nightlight and keep your outlets free! Keeps cool to the touch, lasts over 100,000 hours, and doesn't block you from using your outlets for other things.
