When the light leaves, we don’t.
The Winter Program is your guided season of light — protocols, the clinic, and a personal plan for the darkest third of the year. Included free with every device.
The device is half of it. The Program is the other half.
A full-spectrum panel is the start. The Winter Program is the coaching around it — a seasonal membership that turns a device into a daily habit, tuned to your light as it fades and returns. October to March, when Central Europe loses a third of its daylight and your biology feels every hour of it.
Everything to run your winter on light.
Seasonal protocols
Guided routines that change with the daylight — morning entrainment through the darkest weeks, then the transition back to spring.
The Light Letter
Seasonal guidance to your inbox — what to do with your light this month, grounded in the clinic’s 17 years.
My Light Day
Your personal morning-to-night light schedule, built from your wake time and focus — updated by season.
Ask the clinic
An async line to a named human at the ENDALA clinic. Wellness-framed, real answers — the part no competitor can copy.
Early access & member pricing
First to new devices, member-only offers, and priority through the winter peak.
Free with every device.
Included with any device
Every REDelios ONE — on its own or in the Complete Sun System — comes with your first season of the Winter Program, free. The first thirty days are the product; we make sure you use it.
Or join standalone
No device yet, or into your second season? Join the Program on its own for a modest annual membership.
Always additive, never a takeaway — the Program only adds to what your device already does.
A winter that works with your biology.
Start with a device and your first season is on us.
