Efficient LED Lighting Systems visited the SAU 85 offices to explore the many benefits associated with a conversion of traditional lighting at the Sunapee Middle High School (SMHS) to high efficiency LED lighting. The possibility of making the conversion without capital expenditure was a key point in the discussion. Financing plans and incentive rebates available through the utility company, as well as the purchasing power provided by Efficient LED Lighting Systems, would make it possible for this project to be implemented without any up-front-expense.
A presentation was conducted a school board meeting outlining the project (i.e. associated costs, savings, etc.) facts related to energy conservation, LED light quality, LED equipment life expectancy and product warranties. Additional information was offered on financing and rebates, and many questions were asked by the board. The proposal was approved at that meeting and the plan went into motion.
The improvements, however, are not simply financial and environmental; the LED lighting quality is extraordinary. Utilizing photometric calculations, Efficient LED Lighting Systems recommended fixtures that would provide a balanced blanket of light. Flickering associated with fluorescent lighting is eliminated, and maintenance charges associated with replacement of fluorescent tubes and ballasts is significantly reduced. Fluorescent tube or HID bulb failure occurs at approximately 15,000 hours of operating time, possibly less. DLC listed LED lighting equipment is rated for 50,000+ hours. The LED life expectancy is 3.3 times longer than that of fluorescent or high intensity discharge lamps.
Over the course of the next 8 weeks, fixtures and lamps were systematically installed throughout the SMHS and the installation was completed on-time for the new school year. The town of Sunapee now enjoys a 47% reduction in the costs associated with lighting at the SMHS.
