Replacing 82 HID luminaires on the Univ. of Louisville campus with pole-top LED units cut demand from 100,000 to 12,000 kWhr/yr.

The LEDioc retrofit post-top luminaires were designed to fit on top of the 82 poles that flank the Eastern Parkway on the Univ. of Louisville campus.

The LEDioc retrofit post-top luminaires were designed to fit on top of the 82 poles that flank the Eastern Parkway on the Univ. of Louisville campus.

The Univ. of Louisville, located on the banks of the Ohio River in Louisville, KY, since 1798, has earned its reputation as one of the country’s leading educational institutions. The splendid campus is near the heart of the city and the university prides itself on the architecture of its buildings and the beautifully landscaped grounds. The major thoroughfare into the campus is Eastern Parkway, heavily traveled day and night.

As the final step of a campus-wide lighting retrofit, the university facility-maintenance staff decided to replace Eastern Parkway’s existing 82 250-W high-pressure-sodium luminaires with LED technology. The decision was easier than the implementation. The poles along the road fit the landscape nicely and it was not in the budget to replace them, so they needed a post-top retrofit solution that delivered quality lighting and could be economically installed by maintenance personnel. Several months of searching revealed no product that fit the specification and the current poles, until they connected with EYE Lighting and the LEDioc engineered LED solution. EYE Lighting International of North America Inc. is located in Mentor, OH.

The LEDioc lamp is designed specifically as a retrofit post-top luminaire. Combined with the company’s expertise in custom re-engineering of the mechanical package, the solution for EYE customers such as Louisville becomes attractive financially.

The University’s partner in the project was Eco Engineering, Cincinnati. The company has performed thousands of lighting upgrades in millions of square feet of space. Matt Minard was the project leader. “A primary goal for the Eastern Parkway phase of the retrofit was lighting quality; we needed to assure a superior visual environment for pedestrian and vehicular traffic. We called EYE Lighting because we learned of their growing capability to replace HID post-tops with a custom-designed LED light source. We sent a sample luminaire to their engineering team and the end result was a perfect LED retrofit kit. I believe the EYE LEDioc lamp was the best, if not the only, solution for this application,” he said.

The cost of operating the luminaires was reduced by more than 85%, with kilowatt hours dropping from more than 100,000 to 12,000/yr.

“The installation process was more than a pleasant surprise,” Minard continued. “It took only 20 minutes per pole to replace the old light source with the new 37-W LEDioc. The crew said it was simple and easy. And when the new lights were turned on, the news got even better. The light level is excellent and the bright, crisp visual environment is just what Louisville was looking for. They are delighted with new lighting.

“The EYE Lighting team was easy to work with. They provided superior service and delivered a great product,” concluded Minard.

The cost of operating the 82 Eastern Parkway luminaires was reduced by more than 85%, with kilowatt hours dropping from more than 100,000 to 12,000/yr. Kilowatt demand went from 23.7 to 2.7—numbers that prove LEDioc is the right choice for street and area lighting retrofits.
