Red light panels, run through the numbers
What the measurements say: wavelengths, irradiance at the distance you’ll actually use, size, flicker and warranty. Third-party measurements credited.

Irradiance drops fast with distance. A panel’s headline number is often measured right at the lens. We look for independent measurements at realistic distances and credit who measured them.
Before you buy: what to check
The specs that decide whether it fits your space, your circuit and your budget.
- WavelengthsWhich wavelengths the panel uses and in what mix, from the spec sheet.
- Irradiance at your distanceLook for independent measurements, not only the maker’s number at 0 inches.
- Treatment areaPanel size decides how much of the body it covers at a given distance.
- Flicker and EMFThird-party measurements where they exist, credited.
- Mounting and powerDoor mount, stand or battery; outlet needs.
- Warranty and returnsLength of warranty and the return window.
