A method and device are presented for providing patient safe light to a wound. The device includes a radiation source producing flora lethal radiation wavelengths, a radiation conduit detachably optically coupled to the radiation source, and a patch remotely located from the radiation source configured to at least partially conform to a surface contour of the wound. The patch includes a flexible panel formed of a radiation transmitting material able to withstand sterilization, including at least one surface with a disturbed surface area configured to emit radiation upon the wound.
