Editorial Standards: How We Review Devices

Reviewer applying red light therapy editorial standards with a device checklist

Our Editorial Standards spell out exactly how we evaluate red light therapy devices. Our red light therapy editorial standards ensure every review is transparent and unbiased. Every review and roundup at Red Light Sage follows a transparent, repeatable framework—so you know why a device is recommended and how it was judged. No pay-for-placement. No hidden agendas. Just clear criteria applied consistently.

In the sections below, we break down the five pillars of our review process—wavelength accuracy, irradiance at realistic distance, build quality & safety, usability, and evidence base—plus how we handle testing, updates, corrections, and disclosures.

👉 To see these standards in action, visit our 2025 Buyer’s Guide, read the Benefits (Backed by Science), and review our Safety Guide.

1) Wavelength Criteria 🌈

We verify whether a device emits within the research-backed ranges for photobiomodulation: visible red 620–670 nm and near-infrared 810–850 nm. These bands target both surface and deeper tissues for complementary benefits.

  • ✅ Acceptable: Narrow peaks centered inside 620–670 nm and/or 810–850 nm
  • ⚠️ Watchouts: Marketing claims without spectra; vague “red/NIR” with no nanometers listed
  • ❌ Not acceptable: Out-of-range LEDs (e.g., mostly 700–780 nm “dead zone”) presented as therapeutic

How we check: We look for published spectra, credible third-party measurements, or manufacturer documentation that shows peak wavelengths and bandwidth (FWHM). If unavailable, we flag the claim and lower confidence in the device’s efficacy.

2) Irradiance at Realistic Distance ⚡

Output power matters only at the distance you’ll actually use the device. We prioritize irradiance measured at 6–12 inches for panels and direct/near contact for masks/handhelds.

  • ✅ Acceptable: Independent or transparent measurements reported at 6–12 inches
  • ⚠️ Watchouts: “On-glass” numbers used for marketing; no distance specified
  • ❌ Not acceptable: Inflated claims without test method or unit clarity (mW/cm²)

How we check: We assess provided test setups, meter types, and measurement methodology. When available, we compare multiple sources and consider beam angle, coverage, and dosing time to estimate practical session effectiveness.

3) Build Quality & Safety 🛡️

Reliable engineering reduces risk and supports long-term use. We inspect fundamentals that affect durability, comfort, and safety.

  • 🧊 Thermal design: Effective cooling, safe surface temps, fan noise within reasonable limits
  • 🔌 Electrical integrity: Stable power supply, quality drivers, tidy internal layout (where verifiable)
  • 🧾 Certifications: CE/ETL/FCC or region-appropriate marks; honest documentation
  • 🌫️ Flicker: Low flicker or DC-driven LEDs preferred for comfort
  • 🧱 Chassis & mounting: Rigid housing, secure mounts, safe cables, accessible controls/timers

How we check: We review spec sheets, certifications, teardown evidence (when available), and long-term owner feedback. Devices lacking basic safety assurances are penalized regardless of output claims.

4) Usability & Experience 🧘

A powerful device that’s hard to use won’t deliver results. That’s why our editorial standards include usability. We ask: will a real person be able to integrate this into daily life comfortably?

  • ⏱️ Timers — built-in session timers or external controls for easy dosing
  • 📐 Form factor — size and shape that fit real use cases (desk, floor, wall-mounted)
  • 🔄 Modularity — ability to expand from a single panel to multiple units
  • 🤫 Noise level — quiet enough for daily use without distraction
  • 🪑 Accessibility — simple setup, stable mounting, clear instructions

We rank usability alongside technical specs because consistent use, not just raw power, determines whether users will see results.

5) Evidence Base & Claims Review 📚

Our reviews cross-check device marketing claims with published research. If a brand advertises results that aren’t backed by evidence, we call it out.

  • ✅ Aligned with research — wavelengths, dosing ranges, and outcomes match what PubMed and clinical studies support
  • ⚠️ Exaggerated claims — “miracle cure” language or promises of instant results raise red flags
  • ❌ Unsupported outcomes — no evidence for claims (e.g., curing diseases outside studied scope)

Trusted references include PubMed, Cleveland Clinic, and Mayo Clinic, among other peer-reviewed sources.

6) Testing, Scoring & Updates 🔄

Scoring system and update policy used in our red light therapy editorial standards

Devices aren’t static — models change, specs get updated, and new competitors enter the market. We apply the same red light therapy editorial standards across handhelds, panels, and masks. That’s why our review standards include a clear scoring and update system.

  • 📊 Scoring — each device rated across wavelength accuracy, irradiance, safety, usability, and evidence alignment
  • 🕐 Updates — major guides (like our Buyer’s Guide) reviewed annually or when new evidence emerges
  • 🔧 Corrections — if errors are found, we update content and note the change date

This system ensures our recommendations remain accurate and up to date, even as technology evolves.

7) Corrections, Disclosures & Independence 🛡️

We take independence seriously. Brands can’t pay for placement, and we disclose affiliate relationships openly. If we make mistakes, we fix them quickly and clearly.

  • 📖 Corrections — errors corrected promptly with updated timestamps
  • 🤝 Disclosures — affiliate links marked transparently in each article
  • 🚫 No sponsorships — rankings and reviews never influenced by brand payments

This approach helps maintain reader trust and ensures that our standards stay uncompromised. For more detail, see our Affiliate Disclosure & Privacy Policy.

8) How We Handle Reviews 📝

When evaluating devices, we don’t rely on marketing brochures alone. Our process involves a layered review that combines specifications, independent testing, and verified user experiences.

  • 🔬 Spec review — wavelengths, irradiance, build quality, and certifications
  • 👥 User feedback — verified owners share real-world durability and usability insights
  • 🧪 Third-party testing — lab results or independent reviewer measurements strengthen credibility
  • 🔄 Comparisons — devices assessed side by side within categories (handhelds, masks, panels, modular walls)

This blend of technical checks and user perspectives helps balance the science with everyday experience.

9) Our Network of Sage Standards 🌐

Red Light Sage is part of the broader Sage network, which includes Sauna Sage and Plunge Sage. Each site follows the same editorial philosophy:

  • 📚 Evidence-based — every claim supported by research or clinical consensus
  • 🛡️ Independent — no device sponsorships or pay-to-rank placements
  • 🤝 Transparent — clear disclosures on affiliate partnerships
  • 🔄 Consistent — evaluation frameworks applied across all wellness tools we cover

This unified approach ensures that whether you’re reading about saunas, cold plunges, or red light therapy, you’ll find the same commitment to trustworthy content.

10) Reader Expectations 🎯

We publish with one audience in mind: you. Readers come to Red Light Sage looking for clarity and confidence. That means we prioritize:

  • 🔎 Straight answers — no hype, just science-backed insights
  • 📖 Practical guidance — clear steps you can apply at home
  • 💬 Open feedback — we invite questions and refine content based on reader needs
  • 🧭 Consistency — reviews written with the same scoring system across devices

Our readers deserve honesty, clarity, and action-ready information — and that’s what we aim to deliver every time.

11) Limitations of Our Reviews ⚠️

While we work hard to apply fair, consistent standards, there are limitations to what we can do. Knowing these helps you interpret our content responsibly:

  • 🚫 No medical diagnosis — we share wellness insights, not prescriptions
  • 🚫 No lab of our own — we rely on independent testing, research, and user feedback
  • 🚫 No guarantees — individual results vary by health status, genetics, and consistency of use

Red Light Sage gives you the most reliable, research-backed foundation possible — but personal outcomes will always differ.
