EXISTING CONDITION:

  • This dealership had over 200 of the standard 1000w metal halide fixtures to illuminate the lot
  • While the light is excellent they are expensive to maintain and operate and deteriorate quickly
  • The interior was also using an aging florescent system that was inefficient
  • The goal was to maintain or improve merchandising and reduce cost of both maintenance and energy

EXTERIOR LIGHTING UPGRADE USING PULSE START BALLASTS

The existing system was retrofitted from 1157 total watts per fixture to 630 watts using a hybrid system from Venture lighting. The system maintains lumen output without substantial degradation through the life of the system. The life of the combined system is over 40,000 hours with the sustained lumen output.The system is also robust and is not affected by power surges or lightning like most LED technology. The installed cost was less than 1⁄2 the LED option and the existing heads and poles remained.

 

LIGHTING CONTROL SYSTEM CHANGED TO MAXIMIZE SAVINGS

The existing lighting control system was on all night for security even though they had went to live security on site. The old system couldn’t be made efficient without re-wiring the contactor circuits so that a custom grid could be on all night. A separate timer was added to leave the lights on during store hours and have a 20% grid operating while closed. Sensors were also added to override the system so it would turn on at dusk and off at daylight.

INTERIOR MAINTENANCE AND SHOWROOM UPGRADED TO LED

The existing maintenance and service areas were still using a T12 HO system for the task lights that were un-supported and consuming 265w per fixture. The LED upgraded only is using 72w and has no ballast. The T8 fixtures were aging and the ballasts were failing so these fixtures were retrofitted to LED using the same fixture.The front showroom was using a 200w CFM in an acrylic shell for ceiling illumination. The light was adequate but the fixture life was only around 6 months and the bulb was around $ 80.00. A LED retrofit improved the lighting and appearance of the cars while reducing energy 50% and extending the live cycle by 20 years with current usage. The outside poles were restored to give the lot an appearance of a complete new system.
