CHALLENGES:
The car dealership had existing concrete lighting pole bases on the lot, with heavy gauge wiring running to each location. The challenging thing about this was the distance between the bases. They were atypically far apart, which made it a challenge for us to find the best possible lighting fixture, reflector, and lens assembly to create the necessary lighting levels for nighttime business and security.

Another challenge was limited pole sizing. Existing bolts set in concrete allowed for no more than 25’ poles in a 90MPH wind zone. In order to balance this limitation of pole height with a narrower range of fixture options, we had to run through several models in our photometric software to develop a sound proposal for this car dealership.

The owner of the lot was very helpful in this process. He sent us diagrams and pictures of the car lot, along with a copy of the previous proposal from our competitor. We decided that this client would need more than one options to consider due to the challenges inherent in lighting this facility and the client’s available budget. Ultimately, we were able to show the owner two proposals and the benefit of one over the other.

The original light system for the car lot had used smaller, horizontal burning, metal halide “shoe box” fixtures. The owner had assumed that we would simply replace this fixtures with newer, better models. We did the first proposal based on his requested upgrade, and in the second proposal, suggested something even better for the car dealership.

We proposed a lighting system configured with high-performance vertical burn SVL series lighting fixtures. A larger housing, a better performing reflector, and a sag glass lens, enables these fixtures to consistently and costs effectively generate higher light output.

Using the raw photometric data we assembled, we also created a three dimensional model of both proposed systems.

FINAL SYSTEM PROPOSED:
Both proposals showed the same number of lighting fixtures in use, and the results were overwhelmingly in favor of the SVL series equipment. The lighting levels were more evenly distributed throughout the merchandise area, whereas the shoe-box type fixtures produced too many hot spots directly underneath the poles. There was also insufficient light between the existing pole locations.
