Beacons for our 21st century lighted aids to navigation will never rival the sparkling beauty of the classical Fresnel lens but they sure do spawn incredible intrigue thanks to the powers of digital technology. The old saying, “good things come in small packages,” might aptly describe the latest advancement in LED (light emitting diode) optics manufactured by Carmanah Technologies in British Columbia, Canada, which have been authorized for use in the field of aids to navigation throughout America by the United States Coast Guard.

Though the days of solar powered aids utilizing the 100 year-old technology of incandescent lighting have long been numbered, even recent LED advances could not overcome the need for traditional external solar components – until now. Whereas current solar arrangements utilizing a 12-volt incandescent lighting system must be equipped with at least one external battery, solar panel(s) and cable connections – not to mention internal components such as lamps, a lampchanger and flasher mechanism, the new 600 and 700 Series of Carmanah LEDs eliminate this cumbersome and costly arrangement altogether.

The Carmanah LEDs are a self-contained, compact and quite durable beacons designed to operate flawlessly once installed, with no additional servicing or maintenance necessary for up to approximately 5 years before battery replacement is required. In addition, the LED optic has a life span of up to 100,000 hours or eleven years. By deploying one 12-lb, self-contained 700 Series Carmanah LED, Coast Guard servicing personnel eliminate the arduous task of having to install heavy 75-lb photovoltaic batteries, solar panels and fragile light source components up tall light towers and across rough terrain where many lighted aids are inherently established.

The standard 155-mm red, green, and white acrylic optics that recreational boaters are accustomed to seeing on many of our nation’s buoys, piers and light towers will slowly be phased out as time moves forward and subsequently replaced by optics such as the Carmanah 700 Series LEDs. Though technological advances in lighted aids to navigation won’t stop with the invention of this incredible beacon, it is fascinating to watch the non-stop progression associated with the quest to continually improve our nation’s guiding lights. Even the definition of automation as we know it in the world of ATON seems inadequate to describe how effective and enthralling Carmanah LED beacons are to navigation as they continue to achieve previously unheard of capabilities in lighting technology.

There are two factors that stand out most with Carmanah LED beacons. One, the optic’s reliability is nearly flawless and two, the LED being a compact, all-inclusive unit versus its predecessors with all their external components, presents a 21st century ATON marvel that is best described with one word – “wow!”
