The Lumiglas EX Fiber Optic light allows the light source to be placed between 1-1/2 and 5 ft., or even more, away from the actual sightglass. This light is ideal for situations where vessel space is limited since the fiber optic cable has a diameter of only 15mm (0.6”) which easily allows for viewing and lighting through a single port. It also offers the possibility to place the light source away from vibration or in more accessible locations for routine maintenance.
