Port Schools Join the Green Lighting Revolution
The Port Washington School District has recently started to bring new LED lighting into the district to achieve significant energy savings.
The Port Washington School District has recently started to bring new LED lighting into the district to achieve significant energy savings. The district is now the first on Long Island to have access to this new product specifically designed to retrofit into high bay gym ceiling fixtures. The district has successfully completed 2 projects to replace these bulbs.
The Schreiber and Weber gymnasiums, like thousands of other school gyms, were using 275w High Pressure Sodium bulbs to light their space. Additionally, the bulb requires a 40w ballast, which increases the total wattage of the single bulb fixture to 315. Smart Energy US has manufactures a direct retrofit LED lamp that reduces the wattage to a total of 80, a savings of 74% in electrical costs over the lifetime of the new LED bulb. This particular bulb is rated to last 50,000 hours which is approximately 5.71 years if the bulb is used 24/7. In the case of the school gym, the lights are used only 5 days per week for an average of 16 hours per day. If you account for the weekly hours and school vacations, these bulbs should last approximately 11 years without any maintenance required.
After completing an energy audit of the gym lighting, Smart Energy US recommended an LED bulb designed specifically to retrofit high bay gym fixtures. The school did a mock up of 2 fixtures and it was determined that the application required an LED solution of 80W, 5000K color temp, and a beam angle of 40°. The Return on Investment (ROI) profile for the project is as follows:
