Competitor products have a single optical output at 30° meaning, a single acceptance angle that limits the amount of light absorbed by the body. Our Clearlight Light Therapy units use a combination of 7 - 60° optics to create multiple cross - acceptance angles of light waves. This allows the light to be absorbed by more of our skin to offer more benefit faster with each session. With our Variable Optics™, your body receives pin point light to target specific areas as well as more diffuse light for whole body therapy.
