This is a FULL SPECTRUM light. Its spectrum resembles sunlight: 380 nanometer purple all the way to 840 nanometer infrared.
Our new microwaved world drowns us in a sea of non-native EMFs, we need to mitigate this EMF pollution using sunlight and full-spectrum light devices.
This FULL SPECTRUM light can be worn on the radial artery on the wrist (compare to $750 Quantlet), it can also be used as an intranasal light therapy device (Compare to $399 Vielight). The nasal cavity is rich in blood vessels.
The light delivered to the tissues is absorbed by the MITOCHONDRIA. We need FULL SPECTRUM LIGHT, preferably from the sun, if not, then from full spectrum lights. $59.00 .
