Buying a red light therapy device can be confusing. Here’s what to look for and what to avoid.

Key Specs to Check

1. Wavelength

Most important spec. Look for:

  • 660nm (red) — Skin and superficial tissue
  • 850nm (near-infrared) — Deep tissue, joints
  • Best: Dual wavelength (660nm + 850nm)

2. Power Output (Irradiance)

  • Measured in mW/cm² at treatment distance
  • Minimum: 30 mW/cm² at 6 inches
  • Optimal: 50-100 mW/cm² at 6 inches
  • Higher power = shorter treatment time

3. Treatment Area

  • Small (face): 4" x 4" or mask
  • Medium (single area): 8" x 12"
  • Large (full body): 12" x 24" or bigger

4. EMF Levels

  • Should be low or zero EMF
  • Some cheap devices emit high EMF
  • Look for brands that test and publish EMF data

5. LED Count and Quality

  • More LEDs = more coverage
  • Quality LEDs last longer and maintain power
  • Look for brands that use branded LEDs (e.g., Osram, Epistar)

What to Avoid

❌ No wavelength specs

If the device doesn’t list specific wavelengths, avoid it.

❌ Too cheap ($20-50)

Cheap devices often:

  • Use wrong wavelengths
  • Have insufficient power
  • Emit high EMF
  • Don’t last

❌ “Therapy” lights without specs

Generic “therapy lights” may not have proper wavelengths or power.

❌ No return policy

Reputable brands offer 30-60 day return policies.
