Solar Obstruction Lights Feature Brighter LEDs
After a recent LED upgrade, Flash Technology’s A704-5 solar LED obstruction light can now be deployed as a tower marking light in more locations throughout the world.
The International Civil Aviation Organization (ICAO) publishes Annex 14 that governs lighting requirements for airfields and obstructions in the vicinity of airfields. ICAO Annex 14 low-intensity Type A obstacle lights are for structures under 45 meters in height. ICAO low-intensity Type A specifies “red, steady-burning lights that can produce 10 candelas of intensity.”
New LEDs in our A704-5 solar LED obstruction light deliver a significantly higher candela output than before, allowing a red A704-5 to be set to AUTONOMOUS-MEDIUM and achieve a peak output of 16 candelas. This improved photometric performance means that the red A704-5 will now meet ICAO low-intensity Type A across a much wider latitude band, in locations such as Lisbon, Houston, Canberra, Tai Pei and Buenos Aires.
Available with visible light or with infrared output for tactical applications, solar LED obstruction lights are an ideal solution for marking temporary structures and permanent structures, especially when grid power is unavailable or unreliable. Installable anywhere, the fully self-contained and self-powered lights require no maintenance for up to five years, and the rugged design and proven technology are field-proven to perform in the world’s harshest, most remote environments.
