Before and After — LED relight/retrofit

The below un-altered photographs of “Before” and “After” installations demonstrate LEDs superior characteristics of lighting. LED performance provides better visual acuity and better uniformity which is all achieved while using less energy! Spaulding's Cimarron LED fixtures integrate the latest LED advancements and deliver optical performance that can perform as well as, and in most cases, better than traditional HID fixtures. Additionally, HID/LED comparison charts and sample project cost savings are provided to estimate savings or traditional lighting sources.

 

Kevin Whitaker Chevrolet

Working with Kevin Whitaker Chevrolet, the lighting designers at Net Zero USA chose three different Hubbell Lighting outdoor LED products to make the cars and trucks' paint truly pop. Over one hundred 1000 watt metal halide fixtures at the tops of existing poles were replaced with 332 watt Spaulding Lighting Cimarron LED luminaires. Forty-four 250 watt small metal halide floodlights located halfway down some of the front line inventory poles were swapped out with forty-four 70 watt Hubbell Outdoor Lighting Miniliter LED floodlights. And a dozen 1000 watt metal halide floodlights on the exterior of the building were updated with fourteen 107 watt Hubbell Outdoor Lighting Magnuliter LED floodlights.

Inside the showroom and office space, the dealership chose products from Hubbell Lighting's Columbia Lighting and Prescolite brands to provide an inviting atmosphere for customers and showcase vehicles in the showroom.

TD Convention Center

The parking lot lighting at the TD Convention Center is a prime example for the future of LED lighting.The parking area was lit with 400w HPS fixtures mounted in double configuration at 28 feet. These fixtures were replaced with Cimarron 90LED 210w fixtures on the existing poles. The results included energy-savings of 55% over HPS, improved overall uniformity and a safely illuminated parking area. Reference the HID/LED Comparison chart below for savings of LED systems compared to PSMH and HPS lighting systems.

ABQ International Sunport

The parking area lighting at the Albuquerque International Sunport is another prime example of the benefits of relighting with LED lighting. The parking area was lit with 400w metal halide fixtures mounted in single and double configurations at 25 and 30 feet. These fixtures were replaced with Cimarron 90LED 210w fixtures on the existing poles. The results included energy-savings of 54% over MH, improved overall uniformity and a safely illuminated parking area.
