All electrical equipment emits some amount of electromagnetic radiation. The way red light panels and other red light therapy equipment are engineered is crucial to reducing the number of EMFs they emit.
When looking for a decent red-light panel, seek ones that can confirm they have low EMF and minimal flicker, reducing any unwanted impacts.
You might wonder what a flicker in red light is. Flicker is just a faulty change or intermittent irradiance of light emitted that can occur in any illumination.
If overexposed to flicker, it can cause headaches and strain; therefore, it is advised to always look for red light brands that can guarantee reduced flicker in their panels.
