The all new WilnoLED film viewer has introduced LED technology to NDT/industrial radiography. The efficiency of LED is much higher than of the former halogen lamps because they create only ‘cold’ light totally without heat radiation. The power input required to achieve the needed luminance of the viewing screens is substantially lower than for halogen lamp units. With only low heat to be removed, the fan on the Wilnos LED film viewer is now whisper quiet.
