UV-C lamps shine blue because they emit light in the ultraviolet spectrum, which is not visible to the human eye. However, some UV-C lamps are coated with a phosphor material that absorbs the UV-C light and re-emits it as visible blue light. This process is called fluorescence, and it causes the UV-C lamp to appear blue when it is turned on. The blue light emitted by the lamp serves as a visual indicator that the UV-C lamp is operating and emitting ultraviolet light. **
