Editorial Standards Last updated May 2026

Independent, FDA-cross-checked, affiliate-disclosed.

Red Light Verified is an editorial review site for red light therapy devices. We exist to separate published wavelength + irradiance + FDA 510(k) data from the marketing language that wraps it.

01 — Why we exist The gap we're filling

The red light therapy device market grew an estimated 160% in the past 12 months (Google Trends search interest, May 2025 – May 2026). Most brand marketing confuses FDA cleared (the weaker 510(k) substantial-equivalence pathway) with FDA approved (which almost no red light device has). Most reviews are paid placement. We exist to call this out.

02 — How we test Our four-step verification

Wavelength verification. We require manufacturers to publish specific nm values (e.g., "660 nm + 850 nm"), not vague terms like "red LED". Devices that decline to publish wavelength data get a callout in our reviews.
Irradiance check. We look for irradiance specs published at a realistic treatment distance (typically 6 inches). Devices that publish only "peak irradiance at 0 inches" get flagged as misleading.
FDA 510(k) cross-reference. Every claim of "FDA cleared" is cross-referenced against the FDA 510(k) database at accessdata.fda.gov. If we cannot find a K-number, we report that.
Hands-on use, where feasible. Devices we receive (purchased or sample) are tested for build quality, battery life (for handheld), and user-interface friction.

03 — How we make money Affiliate model, transparent

We participate in affiliate programs with the major red light therapy brands. When you click an affiliate link and buy, we may earn a commission. We do not accept paid placement. Ranking position is never influenced by commission size.

See the full Affiliate Disclosure for the specific programs we participate in and the commission ranges.

04 — What we are not Explicit non-claims

We are not doctors. Nothing on this site is medical advice. If you have a skin condition, consult a dermatologist. If you have joint or muscle pain, consult a physical therapist or sports medicine doctor.
We are not the FDA. When we report that a device is "FDA cleared," we are citing the public 510(k) database — not endorsing the device's efficacy.
We are not a brand-owned property. No red light therapy manufacturer owns or invests in this site. We have no editorial influence relationships beyond standard affiliate links.
