Casper Glow Light

Casper made a bedside light called the Glow that dims gradually over 45 minutes to simulate a sunset. The idea is that it trains your body to wind down instead of just switching from full brightness to darkness. About the size of a candle, the light is a small cylinder. You control it by flipping it over to turn it on, twisting to adjust brightness, and giving it a gentle shake to activate the dimming mode. Those gesture controls mean you don't need to find a button in the dark. The interaction design is physical rather than app-based. The last thing I want before bed is to look at my phone screen. Warm amber tone is noticeably different from the blue-white of overhead lights and phone screens. After using it for a month, I fall asleep faster on nights when I use the dimming mode than when I just turn off my regular lamp. It charges on a wireless base, and the battery lasts about a week of nightly use. Casper designed it as a companion to their mattresses, but it works as a standalone product. At $89, it's cheaper than most smart home lights that require an app and a hub. Gradual dimming changes my bedtime routine. I start getting sleepy before the light is fully off. The passive behavior change is harder to achieve than it sounds. The design treats sleep as something that needs a transition period rather than an on-off switch. The respect for the process is what makes it work. My roommate asked where I got it after noticing I'd stopped using my phone in bed. That's the kind of recommendation that happens naturally because the change in behavior is visible.
