Firefly Portable Red & Near-Infrared Light Device

Light is a nutrient.

When your environment isn't providing what your biology needs, you supplement.

Most people who travel regularly have already experienced the disruption: time zone crossings, hotel rooms, no morning sunlight, circadian rhythm off, sleep worse than at home.

The Firefly exists because a light therapy protocol shouldn't require being in the same place every day.

The Firefly runs on a standard battery bank: no outlet required. It's carry-on sized.

It delivers 660nm red and 850nm near-infrared in a device small enough to sit on a hotel desk or pull out on a plane.

We've had customers use it on long-haul flights. Others use it in vehicles during road trips. Remote workers and digital nomads who spend months in different countries. Parents who want the protocol to continue for the whole family regardless of where they are.
