Date Announced: 05 Mar 2009 New York, NY -- Greenlight Initiative, a New York headquartered LED-lighting sales and solutions provider, announced one of the first commercially successful deployments of an LED-based lighting installation for large exterior marker-sign applications. The internal illumination of the 2 by 8-foot remotely-mounted building marker-sign was based on Albeo Technologies’ state-of-the-art white LED fluorescent troffer retrofit kit directly integrated to the sign’s solar power system. With the installation, the uniformity of the sign's illumination was increased, while power requirements were decreased by as much as 70%.According to Nik Nicolakis, President and co-founder of Greenlight Initiative, “Contrary to some recent comments from the periphery of the LED-lighting industry, solid state lighting is able to demonstrate a clear return-on-investment in key applications currently being served by fluorescent lighting. "Those include real-world installations in commercial, industrial and public sector applications, and we're proud to say that both solar and standard sign illumination can be added to the list. We are very appreciative that, Dimensional Innovations turned to Greenlight Initiative to identify and implement the LED lighting portion of their newest marker sign design."The standard LED-based retrofit lighting kit was internally end-mounted and arranged facing inward towards the center of the two-sided sign. Traditional high-output fluorescent illumination would typically mount four single-lamp T-12 110w tubes at intervals along the length of the marker sign. The LED system’s highly controlled light distribution allowed the same sign to be equivalently illuminated with only 130 total watts instead of 440 watts for the T-12 solution. It is notable that the LED installation is particularly effective with a solar-power system because it is compatible with the “native” 12-volt output of the solar panels and batteries. This eliminates the need for expensive or inefficient inverters and ballasts normally used to supply 110v AC to the fluorescent tubes. The long life of the LED system also greatly reduces maintenance requirements.“On paper, it was clear that an LED lighting system would be the preferred approach for seamless integration within a large solar-powered sign installation,” Dimensional Innovations' R&D Specialist Curtis Shaddox offered. “The challenge continually confronting us was how to separate hype from reality with the technology. We turned to Greenlight Initiative because they have clearly invested themselves in testing and qualifying real solutions that work today. It was quite a pleasant surprise to find that they could recommend an off-the-shelf solution that has performed even better than we could have predicted.” Dimensional Innovations, had several years’ experience with LED modules, and tried a number of installation options, including direct backlighting and custom-module approaches. Through the process, they had not found the combination of quality, performance and price that translated to an encouraging business case. To complicate the challenge, the incumbent fluorescent systems worked adequately, so there was no justification for taking a risk on a customized solution that lacked an equivalent level of performance.“Factoring in the reduced maintenance, the ability of LEDs to run efficiently with a direct 12-volt solar source, the decreased power consumption and the increased quality of the illumination, it's clear that this is yet another case where LED lighting is a superior solution to the incumbent technologies,” concluded Mr. Nicolakis. “Whether it is a solar-powered, or 110/277-volt installation, high-quality LED solutions are available to serve the signage market with a demonstrable business case. Greenlight Initiative’s extensive qualification program has allowed us to identify those solutions for clients such as Dimensional Innovations.” About Greenlight InitiativeFounded in 2006, and with offices in New York, Atlanta, and Quebec, Canada, Greenlight Initiative's mission is to provide clients with LED and other alternative lighting solutions that can replace and outperform incumbent lighting technologies in terms of energy savings, durability, life, and practicality. Through qualitative, real-world testing and laboratory evaluations, Greenlight presents its clients with a broad portfolio of money-saving, low-maintenance, advanced lighting solutions for a wide range of commercial, industrial and municipal applications.
