# Buying a Red Light Device: The Checklist (2026)

> Wavelength, irradiance honesty, treatment area, safety, and evidence match—before you buy a panel.

*Published 2026-07-10 · Updated 2026-07-10 · By Julian Hart*

*Medical disclaimer:* Devices are not substitutes for medical care. Eye disease, photosensitizing drugs, and skin cancer history need clinician input before light therapies.

The short answer

Buy against a **specific use case**, demand **dose-relevant specs**, protect eyes, and keep expectations graded by evidence. See our [red light uses roundup](https://healthcanon.com/light-and-recovery/best-red-light-therapy-uses-2026) and [complete guide](https://healthcanon.com/light-and-recovery/red-light-therapy-complete-guide).

A beautiful panel that under-delivers irradiance at real working distance is an expensive night light.

## How to use this roundup

Work the checklist in order before checkout; skip devices that fail safety or honesty gates.
