*1: Maximum UV irradiance within the irradiation area.

*2: Average time until the irradiance drops to 70 % of the initial level when operated at 25 °C.

*3: Optically connected operation. The light source for cascade operation is designed to minimize degradation of light output at the connected portion when light source is aligned with no gap.
