Parking Garage Retrofit | Honolulu, HIW1PL36
Before - 150W HPS
When Kaiser Permanente Chief Engineer, Garrett Oguma wanted to im- prove the lighting quality of his parking garage structure, while reducing energy and maintenance costs, he contacted Tom Brennan of Eco-Lite, in Honolulu for assistance. Tom thought that this would be an excellent op- portunity to use Magnaray as the best solution available.
Existing 150 watt HPS (174 total watts each) wall packs provided lots of glare, but not truly visible lighting (S/P ratio = .45) Many days, the lights are on 24 hours per day, because of cloudy weather. Because of the existing quantity of HPS units, it was determined to use the Magnaray #W1PL36 (45 total watts each) adjustable flood unit, with clear lens that provides bet- ter quality lighting results (S/P ratio of lamp is 1.62).
A single fixture demonstration convinced the facility manager to make the change. Tom contacted Hawaii Electric to see if a rebate was available for this application. Once all the numbers were crunched, the utility provided a large rebate, based on their specific use!
Savings per year for electricity and maintenance costs for are $30,427! See next page. The fixtures pay for themselves in one year (install not included) not counting the rebate. With rebate the system pays for itself in less than one year!
After - W1PL36, High Uniformity
- Reduced Energy
- Reduced Maintenance
- Increased Safety
- Increased Visibility
