The only light therapy guide that earns nothing from devices
Two people, one evidence base.
One evidence base, two uses.
Hallow cites every claim to a named study, says out loud where the studies stop, and turns that evidence into a routine for the exact device you own.

Evidence that says where it ends
Every claim stays tied to the study it came from.
Earns nothing from devices
Hallow takes no money from device makers or sellers, so no lamp is favoured for any reason but the evidence.
Every claim cites a named study
Each statement points to the study it comes from, by name, so you can read it yourself.
Says where the studies stop
When the evidence runs out, Hallow says so out loud instead of filling the gap.
Built for the device you own
The evidence becomes a routine for your exact device, not for a generic lamp.

Your device, your routine
Three steps from one evidence base.
Name your device
Hallow starts from the lamp or panel you actually own.
Read what the studies say
Each claim arrives with its study, and with the point where the evidence stops.
Follow your routine
The evidence is turned into a routine for that exact device.

One entry, in full
A sample of the format: claim, study, where it stops, and the routine for a desk panel.
Sample entry, written to show the shape of the guide. It is not a recommendation for you.
Claim
Bright light therapy has been tested in many trials on seasonal low mood.
Study
Golden et al., 2005. The efficacy of light therapy in the treatment of mood disorders: a review and meta-analysis of the evidence. American Journal of Psychiatry.
Where it stops
Trials differ in device, dose and timing, so one result cannot simply be copied onto your own lamp.
Your routine
Desk panel, in the morning, seated with the panel in view and your eyes off its surface, at the distance its manual gives.
The evidence first. Then the routine.
Every claim names its study. Where the studies stop, so does Hallow.
