As autumn shortens the days and the clocks go back, the morning light that anchors the body clock fades. The mechanism, and what helps.

Most homes give the body a fraction of the daytime light its clock needs. The camping studies that reveal the gap, the window studies that show the cost, and how to close it.

The autumn equinox falls on 23 September 2026. Why the mornings darken before the evenings, how much daylight is lost each day by latitude, and three things to do about it this week.

Homes deliver too little biological light by day and too much after dark. What the 250 and 10 mEDI thresholds require, why one fixed fitting cannot do both, and two changes you can make tonight.

A free five-minute audit of your evening lighting. Why overhead fixtures cost you the most at the eye, how to light locally instead, and why a warm-looking room can still be too bright.

The Kelvin number on a bulb box describes appearance, not circadian effect. Why two bulbs at the same colour temperature can differ for sleep, and what to look at instead.

Lux was built on a model of human daytime vision, so it cannot describe the light your circadian clock receives. The difference between lux and melanopic lux, and the measurement that fits.

Where the LONVIA Lamp stands, why the manufacturing stage is the slow one, what the Founding Circle reservation involves, and the timeline from prototype to first deliveries.

The founder of LONVIA on why circadian devices multiply, what the Brown 2022 mEDI thresholds actually require, and why the answer had to be a single lamp you want in the room.

A light-sensing system in the eye, separate from vision, sets your circadian clock. Why brightness misleads, and the metric that measures what your clock receives.

Warm, dim light looks calmer, but does it help you sleep? What the research says about warm white, colour temperature, blue light and melatonin in the evening.
