Newtown Community Center RetrofitW4PT5096, W4PY5096
Newtown Community Recreation Center needed to replace aging their HID Tennis, Volley and Basketball lighting system, and asked Tom Brennan of ECO-LITE, Honolulu to bring in the best solution, that would save energy, and improve lighting quality.
Tom immediately contacted Magnaray International to see how this could be accomplished. The timing was right, since Magnaray had just developed their new “array” lighting design, which uses combinations of their 8’ lumi- naires that can use a variety of lamp types.
Selected for these applications, was the #W4PL5096, 212 watt luminaire (each using 4-PL50/41 lamps) with either 2 or 4 luminaires per array, de- pending on location (see page 2). The 2 light arrays were used on the Vol- leyball and Basketball courts, while the 4 light arrays were used on the double tennis courts.
A total of 42-400 watt HID’s were removed, and replaced with 40-212 watt Magnaray® W4PL5096 units for a savings of 55+% in energy use. All sys- tems are now “instant-on” (can be turned off when not needed), so ad- ditional energy savings can be accomplished over the old HID system. For this facility, 83% total savings.
Existing poles were used, but wind loading pole data needs to be verified for each job location. New poles may sometimes be needed. Checking with a local engineer, and the pole manufacturer is all that is necessary. (Extra poles not removed.) Some other positive features of the twin T5 fluorescent system are long lamp life (50,000 hours when used with program start bal- lasts), and higher maintained light output (90% light at 90% life)
