Small enough to sit in your palm, warm enough to change the whole corner it sits in. Milky white light under a soft dome, one button, nothing to configure.

• Soft milk-white glow — the light you want at 11pm.

• One push-button. No app, no remote, no pairing.

• Built-in battery — put it anywhere, no cord.

• Palm-sized — nightstand, shelf, dorm, desk.

The lamp you buy for yourself and end up buying twice.
