How to choose the best Red or Near-infrared Light therapy device
Getting a good red light and a near-infrared light device that’s properly manufactured, last long and offers the exact wavelength over a specific area will depend on the following factors:
The first question you should ask yourself while purchasing the device is
- “What’s the wavelength range of this device”?
- Are they within the proven ranges of 600-700nm and 780-1070nm?
b. Power density:
Secondly, what’s the amount of power/irradiance can this device deliver? What’s their power density in cm2/mw?
c. Size of Light / Treatment Area:
This is very important. What’s the size of the treatment areas? Is it just a little light of lower than 12″ or larger light that can be able to treat half or your whole body at once. Just think about this: would you prefer to be holding a little device for over an hour just for a specific treatment? Certainly not! You will easily get tired using this approach. The device should be convenient and portable to handle.
What’s the lifespan or duration of this device? Any good device should have at least 12 months or longer warranty. What’s your aim for purchasing it? The device you’re using will depend on a specific purpose. There are different devices with varying specifications (for instance, if you want skin health or brain health, the wavelength, power, and even the device type will be affected.
I can’t emphasize this enough: while choosing the red or near-infrared light therapy device, always check the power density and wavelength because there are many fake devices in the market today that are waste of money.
Based on many kinds of research, check out for these recommended specifications:
630-680nm (best wavelength spectrum for red light)
800- 880nm (best wavelength spectrum for near-infrared) or a combination of both a and b.
