Aktilite is Photocure's proprietary light source for use in photodynamic therapy (PDT) of skin lesions in combination with the Metvix cream. The lamp is available in two models: Aktilite CL16 and Aktilite CL128. The difference between the two models is the size of the light field: Aktilite CL16 illuminates areas up to 40 x 50 mm, while Aktilite CL128 illuminates areas up to 80 x 180 mm.

The lamps are equipped with light emitting diodes (LEDs), which emit harmless red light of a narrow spectrum with average wavelengths of approximately 630 nm. Illumination with Aktilite activates the photosensitiser           Fig: Top: CL16, bottom: CL128
in the Metvix cream, leading to selective destruction of the
diseased cells, while healthy tissue remains unharmed.
