High-intensity elevated edge light is used for runways up to 60 meters wide in CAT I, II, and III conditions. The fixture can also be used for medium-intensity runway edge and threshold/end lighting. The 5NQ3850CU fixture also has omnidirectional output for circling guidance. Low maintenance design minimizes quantity of necessary spare parts. No small clips or lens holders are used so lamp changes can be performed in the field by maintenance personnel wearing gloves. Many fixture components are compatible with ADB L861U type fixture to reduce spares requirements. The Edge Light Marker provides superior day or night visibility of edge light location for snow removal or other maintenance operations. It's available with optional high grade retro-reflective bands to greatly increase night time visibility.
