Two options

The first thing to consider is whether you want to place the led device on the spot you want to treat or whether you want LEDs embedded in fabric that you can strap on your body.

Strap-on led devices

Strap-on led devices sound easier, but they take a long time to produce results because they are very low power. There are many complaints in front of the FDA due to burns from strap-on LEDs. Usual treatment times for one area are about 20–30 minutes.

Handheld LEDs

Handheld LEDs are great if they are powerful. Look for one with 5,000 milliwatts or higher. The higher the power the faster the results. Usual treatment times are 1–2 minutes for one area.

Lower power LEDs

Lower power LEDs take a long time to treat any significant injury. Look for an LED with 5,000–10,000 milliwatts as treatment times are very fast: usually 1–2 minutes per area. You can find devices like this through physical therapy and chiropractic dealers, Amazon, and other online stores.

Lasers Are Coherent, LEDs Are Not

The photons emanating from a laser are highly organized, directional, and termed “coherent light.” Note in the picture below how the laser light is coherent, or “in-phase” and the LED light is non-coherent or “out of phase.”

How Do We Measure Wavelength?

Light travels in a wave as depicted in the diagram below.

We can characterize the light by its wavelength, which is the distance between successive peaks (or valleys) in the wave. We measure the wavelength of light in nanometers (nm).

Measure Light Wave (sine wave)

The length of 1 nanometer is 1 billionth of a meter. One thousand nm’s equals one micron, which is a millionth of a meter. Thus, a 940 nm laser has a wavelength that is almost one micron. By comparison, the size of this dot ( . ), used as a period, is about 400 microns or 1/64 inch.



If you have been suffering from chronic pain, LZR UltraBright can be very effective to alleviate very much your suffering by simply applying an array of led lights to the painful spot of your body periodically and accordingly to the usage directions of the LED therapy or LED light  treatment.

After two days or so, it is noted that applying heat to increase the flow of blood that will result in generating or persuading vital nutrients to recover the damaged tissues, cells and related components of the affected part of the body. This is the recovery stage where pain is reduced by means of the LED therapy or LED light treatment, if and only if, the application will be approved by a qualified  Chiropractor.

Please note that with a sufficient powerful infrared radiation focused on the subject injured area of the body, it will penetrate to the actual internal areas or parts where the injury occurred or it will reach the most internal parts of the old injury or chronic pain to alleviate or lessen the pain towards the end of the final stages of the healing process.

LED devices used in LED therapy or LED light treatments are specifically useful and can be the best remedy or solution for these type of pain or injury situations because the levels of lights can be controlled or set at different frequencies or outputs. Plus considering that the device itself have a long lifetime as long as the LED devices are  handled and stored correctly. Therefore your light or LED therapy will continue as long as the devices will remain functional or undamaged in the many years ahead.
