The tube is made of special glass and filled with a special gas to produce light radiation in the Near Infrared range. The tube is intended for installation or replacement of similar tubes in Diacom-Plazmotronic devices. When replacing, care must be taken not to damage the tube and not to cause cuts or wounds. The tube is installed in the device in the off state, in order to avoid accidental electric shock. This process is recommended to be performed by a trained professional who has the skills to handle devices with AC power supply.
