Works With the Lamps You Already Own
Light is how your body tells the time
For most of human history, the only clock anyone had was the sky.
Bright and blue overhead at midday, low and orange at sunset, black after that. Modern lighting flattened all of it into one setting and left it there.
Full-spectrum white in the morning, the way daylight is
No blue wavelengths in the evening, the way firelight never had any
Deep red at night — the faintest signal there is
One Bulb. Every Room, Every Hour.
Common Questions
-
It's 7W. A traditional bulb giving similar warm light burns around 60W and lasts a fraction as long. If you've been buying old-style bulbs to get warmer evening light, this replaces them and costs less to run.
-
No. Most cheap LEDs flicker hundreds of times a second — you don't see it, but it's part of why some rooms feel tiring to sit in. This one is flicker-free, so it stays steady whether it's on for ten minutes or all evening.
-
It fits any standard screw-in lamp — the regular Edison screw base (E27) used in most table lamps, floor lamps and ceiling fittings. It won't fit smaller candle bulbs (E14).
-
Flick the wall switch or lamp switch off and back on. Each flick moves it to the next mode. No app, no wifi, no hub, no remote to lose.
-
400–600 lumens depending on the mode — roughly the same as a 40–50W old-style bulb. Right for a bedside lamp, a floor lamp or a small ceiling fitting. It isn't a floodlight, and it isn't meant to be.
-
No. It isn't dimmable and shouldn't be used in a fixture with a dimmer. It's built to change modes with a standard on/off switch instead, so it works in any normal lamp.
-
Rated for 50,000 hours. Used every evening, that's roughly ten years.
