Meridian One
Bright and clear through the working day. Deep amber by evening. And after ten at night, not one photon of blue. Your body has told the time by light for two hundred thousand years — this is a lamp that respects that.

The light
This is the actual programme the lamp runs — not an illustration of it. Drag through twenty-four hours and watch the colour, the brightness and the blue content move together.
Amber and low. Melatonin gets going about here, and nothing on this lamp interrupts it.
Colour is computed from the temperature in kelvin using a standard approximation of the Planckian locus — the path a black body traces as it heats up. It's the same maths that decides what a candle flame or a filament looks like. Its range runs from 5200K at noon down to 1800K — about the colour of a candle — and it stops emitting blue altogether at 21:54.
Why
For almost all of human history, the light after sunset was fire. Orange, dim, and flickering — somewhere around 1800 kelvin. Nothing in the evening was ever blue, because nothing in the evening could be.
Then we lit our houses at six thousand kelvin and wondered why nobody could sleep. The receptor that sets your body clock isn't the one you see with; it's tuned almost exactly to the blue that a screen and a cheap bulb put out most of. Give it that at eleven at night and it will confidently conclude that it's the middle of the morning.
Meridian One is the same idea as a candle, run properly. It gets the bright, cool light your body wants at nine in the morning genuinely bright and genuinely cool. And then it lets go of it, in the evening, completely.
A lamp shouldn't argue with the hour it's in.
The range, end to end
Meridian One works between 1800K and 5200K. The cheap tuneable lamp on the shelf next to it bottoms out around 2700K — the third mark along — and calls that warm.
Inside
Most tuneable lamps mix a warm white and a cool white and call it a spectrum. Meridian mixes six, including deep red and true amber, so the bottom of its range is a colour those lamps simply cannot reach.
Tell it your postcode once. It works out sunrise and sunset for your latitude, every day of the year, and shifts the whole programme with them — so midwinter feels like midwinter and not like a calendar reminder.
One brass dial. Push to wake, turn to override, and it returns to its programme by itself an hour later. There is no account, no pairing, and nothing to update.
“I put it on the desk expecting a gimmick and found myself going to bed at a sensible hour for the first time in a decade.”
“The only tuneable lamp I've measured whose evening setting is where it claims to be.”
“It is a very expensive way to own a candle, and I regret nothing.”
