How to Choose a Red-Light Therapy Panel
Six practical checks for choosing a home red-light panel without getting lost in wavelength lists or marketing language.

1. Start with coverage
Panel size determines how much of your body can be illuminated from one position. Before comparing wavelength counts, decide whether you need targeted use, tabletop coverage, torso-scale coverage or something closer to full-body.
2. Read wavelength claims correctly
Wavelengths are measured in nanometers (nm). Red-light devices often combine visible red and near-infrared wavelengths. A longer list is not automatically superior; what matters is whether the device is well specified, appropriately powered and practical for the intended use.
3. Compare irradiance at distance
Irradiance is power density, commonly expressed in mW/cm². A useful number needs a measurement distance. EMR-TEK, for example, publishes distance-specific values for some products. Compare like with like.
4. COB vs SMD
COB (chip-on-board) groups multiple emitters into a concentrated package, while SMD designs distribute individual LED packages across a board. Neither label should replace actual output and coverage measurements. Treat architecture as one input, not a health-outcome guarantee.
5. Check flicker and setup
Some buyers care about flicker percentage, EMF measurements, controls, fans, stands and hanging systems. These details can matter to everyday usability even though they rarely make the headline.
6. Follow the device instructions
Use manufacturer guidance for distance, duration, eye protection and device placement. EMR-TEK’s current pages state that its products are for general wellness and are not intended to diagnose, treat, cure or prevent disease.
