Glo Nightlight with Portable Balls is a great night-light for a kids room. Kids will love to play with the glowing balls. The balls are removable from the lamp base and stay glowing for up to 30 minutes. There’s no electronics or battery needed for the balls, in other words, they aren’t fragile, which makes them ideal for kids. The lamp base lights the glow balls using LED technology, which is efficient and runs cool to the touch. Kids will have lots of fun changing the lamp light color by moving a sliding lever on the base, or keep colors circulating all night long. Kids can also take the balls into bed helping them fall asleep. The ball becomes a companion when they need to get up to go to the bathroom when dark. Parents should not worry about the built materials of the glow balls as they are kid safe. The Glo balls are BPA and PVC-free.
