The present invention provides an apparatus and method for self-tanning or light therapy treatment at home using a device capable of emitting ultraviolet radiation to achieve a tan on the user's body. The invention can also be configured for use in light therapy applications. A complete tan is achieved by lying on a flat surface underneath the apparatus emitting ultraviolet radiation and controlling forward and backward movement of the apparatus along a flat surface by either manually sliding the apparatus along the body or by means of a motorized drive system to focus the ultraviolet radiation on different parts of the body.
