Roul shares his personal experience with the Essential 4" LightTower. The Essential 4" LightTower is EMF protection and so much more. Using physics of light, Essential Energy Solutions line of EMF protection devices creates a harmonized, biophotonic field of energy that shields users from non-native electromagnetic radiation by acting as a tuning fork at the biophysical level. Active bioresonance Essential Energy doesn't block electromagnetic fields, but rather produces a resonance that strengthens the biofield of people, plants and animals, shielding it from EMF stress. The result is greater energy, balance and normalized response to EMF stress.
