Red Light Device Buying Checklist: Ten Specs to Compare
Quick answer: Compare devices on measurable specs: wavelengths, irradiance at a stated distance, coverage, size, run time, cord or battery, warranty, support, safety guidance and price. Ignore vague terms such as medical grade. This is a shopping guide, not medical advice.
The checklist
| Spec | What to look for |
|---|---|
| 1. Wavelengths | Stated in nm, such as 660 and 850 |
| 2. Irradiance | mW/cm2 at a stated distance |
| 3. Coverage | Emitting area in inches |
| 4. Size and weight | Does it fit your space |
| 5. Run time | Timer or auto shut off |
| 6. Power | Cord length or battery type |
| 7. Warranty | AWA panels carry 2 years, other devices 1 year |
| 8. Safety guidance | Clear eye safety notes in the manual |
| 9. Clearance wording | Select devices carry FDA 510(k) clearance for specific, limited uses. Most are sold as general wellness products. |
| 10. Price and payment | Many AWA devices are FSA and HSA eligible |
Putting it to use
Compare the FX300 and FX500 using the measured values in our irradiance specs. For belts and blankets, compare coverage and run time instead. See the belt and the HL300 blanket.
Common mistakes
- Choosing by LED count alone.
- Comparing irradiance measured at different distances.
- Trusting clearance claims without checking. Read how to verify a device's FDA claims.
