This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This trial is testing whether a special light therapy device called Luminette® can help prevent chronic cluster headaches from happening. Cluster headaches are severe, recurring headaches that tend to follow patterns in your body's natural rhythms — similar to how seasonal depression works. Researchers think light therapy might help reset those rhythms and reduce how often attacks occur.
Chronic cluster headaches are hard to treat with current medications, and doctors believe they may be linked to disrupted daily biological rhythms. Light therapy has already helped people with other rhythm-related conditions like seasonal depression and migraines, so researchers want to see if it could work for cluster headaches too.

You will be randomly assigned to use either an active light therapy device or a placebo device that looks identical but uses different light wavelengths. You'll wear the device during the study period — likely using it at home each day — while keeping track of your headaches. Researchers will monitor how many cluster headache attacks you have over time to see whether the active light therapy reduces them compared to the placebo.
