Red light through the hand

It has been said that to be effective, the red light source should be able to be seen through the hand. According to this concept, if red light can pass through the hand tissue and be visible from the other side of the hand, then it has a chance of being able to penetrate through the skull and into the brain.

We put one of the visible red 670nm LEDs used in our Well Red Coronet (and CoroNase) to the Hand Test.

In the photo below, you can see Ron’s hand. Underneath his hand is a single visible red 670nm LED light, the same as we use in the Well Red Coronet and the intranasal CoroNase. In fact, those who use a CoroNase might recognise the black cable snaking out from under Ron’s hand. Ron used a CoroNase for this test.

There is absolutely no doubt that the light from this one LED shines through his hand - very easily.

So just one of our 670nm LEDs has cruised through the Hand Test!

Here’s Ron’s hand showing the single 670nm LED light shining through.

The above photo was taken in dark conditions. Ron thought it would be interesting to see how well the LED shone through his hand in daylight.

Eureka!

The red light is very visible through Ron’s hand in daylight conditions.

We knew this LED was high-powered and this little experiment has confirmed it. Just one of our 670nm LEDs easily passes the Hand Test in daylight.

These photos show just one LED at work. Only one!

The Well Red Coronet uses 40 of these high-powered and high-quality visible red 670nm LEDs. They work in synchrony and generate an extremely bright and penetrating light dose during the first 12 minutes of the 24-minute session.

The light output shown in the photos is only one fortieth of the total light dose delivered to the whole of the head in the first 12 minutes.

As well as the 670nm, the Coronet has 40 high-powered near infrared LEDs - 810nm - and this is the wavelength with the best penetration profile.

We have as yet unpublished evidence that the light from the Coronet reaches the outer part of the brain. We knew this must be so because of the extensive and consistent reporting of clinical benefits, but it was wonderful to see the evidence from a functional MRI study. We will release this research when it has been published.

So whether or not you think that the Hand Test is valid, it can be seen that just one of the visible red 670nm LEDs used in the Duo Coronet and CoroNase whizzes through the hand and is very very visible on the other side.
