ICAO Annex 14
230V AC / 48V / 24V DC
Auto Standby Switchover
NMS Fault Alarm
Medium Intensity Type B — Dual Voltage Standby with Fault Monitoring
High-intensity (>2000 cd) twin-dome standby aviation light with automatic switchover. Ensures continuous obstruction marking for tall structures even if one light fails. Dual voltage + NMS alarm for maximum reliability.

Standby Control System
- Primary light runs normally — standby is dormant
- Failure detection = current below 65% of rated
- Automatic switchover to standby light on failure
- NMS alarm (potential-free NO/NC) on light failure
- Single photoelectric sensor for both lights
- Single stand mounts both lights
- 3-core cable required between lights and panel
- Junction box included
FAQ
Frequently Asked Questions
Two aviation lights connect to a single control panel. Under normal operation, only the primary light runs. When it fails (current drops below 65% of rated or total failure), the control panel automatically switches ON the standby light. A 'light fail' NMS alarm is raised simultaneously via potential-free contacts.
Most LED aviation lights mount LEDs on flat PCB faces, creating light streaks. Spaceage's unique circular LED mounting achieves fully uniform 360° intensity without secondary optics — meeting ICAO requirements at every horizontal angle.
Available in 230V AC, 48V DC, and 24V DC. Dual voltage models ensure continuous operation from battery backup during mains failure. See model selection table for specific codes.
