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!
