<strong>HID</strong> <strong>vs</strong>. <strong>LED</strong> CASE STUDY<br />
SIGNIFICANT ENERGY SAVINGS WITH NEW OUTDOOR <strong>LED</strong> LIGHTING<br />
<strong>Cooper</strong> Lighting upgraded existing 400W metal halide area/site lighting fixtures<br />
with <strong>LED</strong> luminaires at its corporate headquarters in Peachtree City, GA.<br />
The results are significant. The <strong>Ventus</strong>TM luminaire, which features 12 LightBARTM optics, consumes only 309W compared to 458W from the metal halide fixtures,<br />
while still providing the recommended light levels. In addition, the<br />
Accu<strong>LED</strong> OpticsTM system provides shaped light distributions creating even,<br />
uniform illumination exactly where needed. The new lighting also provides a<br />
benchmark warm white light of 4000K correlated color temperature (CCT) with no<br />
sacrifice in lumen output or lighting performance. The fixtures have a projected<br />
average rated life of 50,000 hours, which is six times longer than the previous<br />
system.<br />
CONTROL IMPLEMENTATION<br />
A <strong>Cooper</strong> Controls system was implemented to change light output (lumens) and<br />
decrease the power supplied to the fixtures during curfew hours. By varying the<br />
number of LightBAR optics being illuminated at a given time, additional energy<br />
savings is achieved.<br />
• For pedestrian safety from dusk to 10:00 p.m., the <strong>Ventus</strong> operates at<br />
full power using all 12 LightBAR optics, which still provides 33% in<br />
energy savings compared to the older metal halide fixtures.<br />
• From 10:00 p.m until 1:00 a.m., the fixtures are powered down<br />
using eight LightBAR optics resulting in a 55% energy savings.<br />
• From 1:00 a.m. until 4:00 a.m., the fixtures use four LightBAR<br />
optics resulting in 77% energy savings.<br />
• From 4:00 a.m. until dawn, the fixtures are back up to full power<br />
(12 LightBAR optics) to illuminate the parking lot for employees<br />
coming into work, still resulting in a 33% savings.<br />
VENTUS LUMINAIRE KEY FEATURES<br />
4000K CCT STANDARD: With typical <strong>LED</strong> outdoor area products<br />
standardized on a cold blue color temperature (6000-6500K CCT) to drive<br />
performance, the <strong>Ventus</strong>’ desired 4000K color temperature meets/exceeds<br />
competitor photometrics with no sacrifice in lumen or lighting performance.<br />
ACCU<strong>LED</strong> OPTICS SYSTEM: The Accu<strong>LED</strong> Optics system features a choice of<br />
15 unique optical distributions to satisfy every application need with more task<br />
lumens, with efficiencies as high as 95%. Each optic produces 100% of the<br />
distribution shape. Individual optics are not aimed to specific portions of<br />
the beam.<br />
LIGHTBAR TECHNOLOGY: <strong>Ventus</strong> is offered in two to twelve LightBAR system<br />
configurations, rivaling 70W to 400W <strong>HID</strong> solutions, respectively. Each LightBAR optic<br />
produces nominal 1750-1850 lumens (depending on distribution) and consumes 26W<br />
each (board and driver).<br />
40°C AMBIENT RATING: <strong>Ventus</strong>’ ambient rating of 40°C ensures the fixture operates<br />
cooler and can safely perform in high ambient temperatures. The LightBAR optics are<br />
IP66 rated and each luminaire comes standard with a 10kV surge suppression<br />
providing industry leading protection against surge failures.<br />
