The Glow charges on a wireless charging pad, allowing you to pick it up and move it around freely. Casper says that it was designed to be used when you're the most sleepy, so it has no top side or bottom side, allowing you to place it in any orientation. Flipping it switches the Glow on, rotating it increases or decreases the brightness, and wiggling it will turn on a small amount of light.
Similar to Night Shift on iOS and macOS, the Glow was built to ensure that the user doesn't face any harsh bright lights right before bed, which could disrupt sleep patterns. The default mode on Glow is a 45 minute cooldown that gradually dims the light until there is none, and in the morning it will gently wake you up by filling the room with soft light.
Multiple Glows can be synced in one bedroom, so that when one is controlled they both adjust light to match one another (up to six can be connected via Bluetooth). You can buy the Glow today for $89 in a single pack or $169 in a double pack.
