Headache, Migraine

Brief summary

Study volunteers are asked to use the Allay Lamp routinely during the 6-week study period. A web based survey is provided when the Lamp is purchased for study volunteers to complete. A daily usage paper diary is sent with the lamp so that volunteers can keep track of the frequency and duration of lamp usage and any noticeable benefits. At the end of six weeks a second survey is sent to study volunteers to capture their perceptions of potential lamp benefits with respect to headache frequency and their experience of migraine specific symptoms.

Interventions

The Allay Lamp is a consumer product currently available and widely used in the US. It emits low intensity (1-10 lux) narrow band (20 nm) green light (peak wavelength 520 nm) that is marketed as non-irritating to users. In that context, it is not a medical device and does not require a 510(k).
