A protective case for a mobile electronic device is provided. The case includes at least one light emitting diode that emits electromagnetic radiation in the range of UV-C light for sanitizing contaminated surfaces. The case also includes additional LEDs that emit light at wavelengths known to have a therapeutic effect such as a blue light for treating seasonal affective disorder. The LEDs are provided in a separate encasement that is detachable from the protective cover configured to receive and protect the mobile electronic device. A short-range wireless receiver is included to communicate with an application installed on the mobile electronic device for controlling the activation, intensity, duration and mode of the LEDs including predetermined treatment or sanitization protocols.
