On December 7th 2012, USIGT, in conjunction with D5 Enterprises, retrofitted and upgraded the existing Metal Halide (MH) building wall pack fixtures at 466 W. Fallbrook for Dana Butcher and Associates in Fresno, CA with CeramaTek (C-Tek) bulbs/ballasts. The project consisted of retrofitting (4) 175 Watt MH wall pack fixtures to 210 Watt CeramaTek. The existing fixture housings were in bad condition and had to be replaced. After consulting with Dana Butcher and his team, the goal of the project was to provide the highest quality light and maximize energy savings. CeramaTek was selected as the preferred technology due to its performance, light output and energy efficient operating system wattage. Retrofit time per fixture was less than one hour per fixture with standard hand tools and can be performed by any electrician or maintenance personnel. A ladder truck was needed for the wall pack fixtures that are mounted +/- 16’ above finish grade. Existing circuits were 120 volt.
The original lighting load was 3.5 kW. This retrofit project increased the lighting load only 2.5%. The environmental impact of this lighting upgrade was neutral. With the outstanding color rendering index of Ceramatek, the quality of light in the parking lot is greatly improved. Retrofitting existing fixtures with eHID high efficiency technology allows facilities to maintain the same high quality of light intended in the original design. Additionally, utilizing existing fixtures, whenever possible, eliminates unnecessary waste to landfills. High efficiency CeramaTek kits produce an industry leading 120 Lumens per Watt (Lm/W) with 95% lumen maintenance at 50% of lamp life allowing for substantial reductions in wattage required per fixture.. The outstanding color rendering CeramaTek technology increases the effective light and more closely resembles actual daylight conditions.
All comparative measurements and photographs were taken at identical times of day and from the same physical location.
