Low intensity XLFE-4/1 LED Obstruction lighting fixtures


Low intensity XLFE-4/1 LED Obstruction lighting fixtures for zone 1, 21

  • Zone 1, 2, 21, 22
  • Obstruction warnings
  • LOW INTENSITY LED technology
  • Lamp lifespan more than 10 years
  • Complies with ICAO, FAA

XLFE-4… /1 series low intensity lighting fixtures are suitable to be installed on towers or high buildings as obstacle signaling devices thanks to the high power and luminous efficiency light source making full use of the experience gained in the world of LED lighting in the recent years. The XLFE-4… /1 lighting fixture, red in color with a luminous intensity of more than 32 candles, complies with the ICAO Annex 14 standard for low intensity aviation warning lamps type A and type B (corresponding to the FAA L-810). The XLFE-4… /1 series is equipped with an internal reflector in chromium-plated anticorodal aluminium alloy and it can be provided with double circuit (main/spare). They are also available for industrial signaling in flashing operation and with different light colors upon request.
