How to choose a red light therapy panel: 2026 buyer's guide
Panels range from $150 to $6,000 and the marketing is loud. These are the specs worth comparing, in order.
1. Normalized irradiance
Compare irradiance at the same distance, not the headline number. We normalize every panel to 15 cm so you can rank them honestly. See irradiance explained.
2. Wavelengths
Look for output concentrated in 630-680nm (red) and 800-860nm (near-infrared). Match the mix to your goal - see 660 vs 850nm.
3. Coverage and panel type
Targeted panels treat one area; half- and full-body panels cover more at once for more money. Decide by use: a handheld for spot treatment, a full-body for whole-body sessions. Filter the database by type.
4. EMF and flicker
Some buyers care about low EMF and low flicker. Good panels publish both. See EMF and flicker.
5. Testing, warranty and value
Third-party testing and a multi-year warranty signal a serious brand. Finally, weigh price against comparable irradiance and coverage - our value score does exactly this. Start with best value panels.
FAQ
How much should I spend on a red light panel?
Quality targeted panels start around $200-300; half-body around $600-1,100; full-body from $1,000 up. Compare value, not just price - our value score weighs irradiance and coverage per dollar.
What is the most important spec?
Irradiance compared at the same distance, alongside the right wavelengths for your goal. Headline irradiance measured at the surface is the most common way buyers get misled.
