LED REIL System (Runway End Identification Light)

LED REIL System (Runway End Identification Light)

Complies with:

  • ICAO Annex 14 Volume I par. 5.3.8
  • FAA L-880(L) / L-881(L) AC 150/5345-28
  • TP 312 par. 5.3.16.12 and Appendix 5B, Figure B-19

 
Features:

  • Long-lasting LED technology ensures extended operational life reducing maintenance and replacement costs
  • Unified design for Styles A, C, and E REILs; all use the same components with style selection via control board configuration
  • Operates at very low internal voltage compared to traditional xenon flash lamps (2000 VDC), enhancing safety
  • Eliminates ozone generation, preventing internal component degradation and improving system expectancy life
  • Consumes up to 90% less energy than xenon flash lamp systems
  • Includes external alarms for critical faults: power loss, LED failures (≥25%), and configurable misfire limits
  • Powered by a constant current regulator (CCR), removing the need for isolation transformers in current sensing
  • Robust trigger design allows use of standard 16 AWG, 600 V unshielded wiring for simplified installation
  • Compact, lightweight, and NEMA 4 rated enclosure ensures durability and ease of installation in harsh environments
  • PAR-56 flash head can be remotely installed up to 100 feet from the control cabinet on 2-inch EMT conduit
  • Operates reliably across a wide temperature range (-40 °F to +131 °F) and full humidity spectrum, including condensation
  • Designed to withstand altitudes up to 10,000 feet and wind speeds up to 150 knots

 

Runway End Identifier Lights (REIL) are critical components in airport lighting systems designed to provide high-intensity, flashing visual cues that clearly mark the runway threshold for pilots during approach and landing. Utilizing advanced LED technology, modern REIL systems offer superior brightness and color saturation, ensuring excellent visibility even in low-light or adverse weather conditions such as fog, rain, or haze. Compared to traditional xenon flash lamps, LED-based REILs consume significantly less energy-up to 90% savings-while delivering longer operational life and reducing maintenance requirements, which translates into lower operational costs and improved airport safety. The low-voltage operation of LED REILs also enhances safety for maintenance personnel by minimizing electrical hazards.

LED REIL systems are built to perform reliably in tough conditions like extreme temperatures, high humidity, rain, dust, and salty air. Their compact, lightweight design with NEMA 4 rated enclosures makes installation and maintenance easy. They work well at high altitudes and strong winds, and many include fault detection and alarms to ensure safe, continuous operation. With better visibility, energy savings, and durability, LED REILs are a smart upgrade for modern airports.
