'Light4health' is a subsidiary of Blue Sun Energetics LLC. We offer a range of services and products to support the mind, body and spirit. Our foundation is the understanding that 'life heals itself' as we identify and release the factors preventing self-healing. The technologies on our site are safe, effective and simple to use for home or professional use. These are devices we use personally and have shared with hundreds of clients and customers. We, David and Erina Cowan, are available as speakers and trainers in the area of stress reduction, peak performance, and personal development. The Cowan's are published authors and are frequent guests on internet radio talk shows.
