A portable, mains electricity (AC-powered) lamp intended to emit low-level narrow-band (LLNB) red light (e.g., 600-650nm) and blue light (e.g., 415-440nm) either separately or simultaneously for photodynamic therapy (PDT) applications (with photosensitizing agent) to treat skin disorders such as actinic keratosis and non-melanoma skin cancer, and for phototherapy applications (through modification of skin metabolism) to treat skin complaints such as acne, rosacea and sun spots. It uses light-emitting diodes (LEDs) to produce a heatless light source which may be used for treatment at multiple anatomical sites. It is intended to be used by a healthcare professional in a clinical setting.
