LED Lighting for Wind Turbine Research Project on Lake Erie
The Renaissance Group of Cleveland Ohio was brought in as the designer, contractor and manager for a wind turbine research project on Lake Erie as well as update of the renewable energy system at the structure. The bright orange 105 year old 80' diameter structure, which is part of the water intake system for greater Cleveland, located 3.5 miles from the harbor, was utilized as the base for the wind monitoring systems.
A 165' 6000# tower was erected for the automated research study, which holds 21 weather instruments.
In the process, Renaissance Group recommended to the City of Cleveland Utility Department that an upgrade of the single existing FA250 private aid to navigation light be undertaken.
This change was planned to essentially eliminate bulb changes and improve visibility on the well known year round navigational aid approaching Cleveland. At the same time, great attention was paid to installing a new system which could autonomously operate under solar power and batteries for extended periods.
After study of all products available, The Renaissance Group recommended and later installed a field test unit of the new CR-SixLED Retro Marine Light Engine in a 305mm lantern. CR's optional sync unit was added, so that the new lantern and old FA250 would operate in unison.
In the initial evaluation of the single LED lantern with the existing FA250, night time visibility of the LED system was clearly sharper and whiter in brilliance as viewed from shore over 3.5 miles away.
The new product performed perfectly for a full year. In October 2006, the lantern was moved to its final location on the tower, and a second identical lantern added for the final design to meet Coast Guard regulations.
The FA250 was decommissioned, and the two CR-SixLED Retro Marine Light Engine lanterns now operate in unison, without any sync module required.
