Comprehensive lighting upgrade to LEDs simplifies complex lighting.
Thermo Fisher Scientific, Asheville, NC, began looking at LED lighting for its facilities several years ago and evaluated a number of manufacturers, distributors, and installation companies.
According to Scott Self, director of energy at Thermo Fisher, they couldn’t find a solution that fit their needs and financial requirements. “The first costs were either too high or the deployment costs were too great to make it economically feasible. We started a dialog with Cree Inc., Durham, NC, to discuss the challenges we were facing. We basically said we feel confidant Cree products are rock solid; we just need the specified return on investment (ROI), or better, to move forward with the project. Cree was able to deliver the products we wanted at the ROI we needed. That’s how the project got started.”
The large-scale project included
replacing almost 2,000 fluorescent high-bay lamps, along with wrapped and recessed strips and troffers. Cree CXB series LED high-bay/low-bay fixtures replaced more than 580 fluorescent lamps in the 25-ft.-high production area, and the LS series surface ambient luminaire, in 4- and 8-ft. lengths, replaced more than 600 fluorescent strips to bring deliver light to task areas of the facility.
Outside, facility parking lot and building lights were replaced with XSP series pole-mount and wall-mount luminaires. When the office lighting was replaced with Cree ZR troffer series luminaires, Stephanie Nilsen, director of operations, noted the positive effect the new lighting had in her environment. “It was immediately noticeable in the office space as it rolled out in my area. I felt more awake at work; I felt more in tune and alive, and it felt very energizing.”
Steve Haney, maintenance manager for the Asheville site, received positive feedback on the new lighting as it was installed throughout the plant. Haney heard from employees that the improved light levels created a more comfortable work environment. The better lighting also impacted quality, commented Haney. “Naturally you can see what you’re doing better and spot defects in the workmanship easier with the lights we have now.” He heard the most feedback on the exterior lighting at the facility. “The lights really lit the outside areas and people felt more secure coming into and leaving the facility in the early morning
have areas in the plant for parts inspection and assembly processes and when a light goes out, as trivial as it may seem, it is critical.” Before production could begin again, Haney had to send someone with the necessary equipment to repair the light, costing time and money. In addition to outages throughout the year, Haney managed a scheduled lighting-maintenance process during the facility’s summer shutdown that required four The lighting had a positive impact on quality, allowing defects in workmanship to be spotted easily. people working full-time to replace bulbs and ballasts—at an annual cost of almost $10,000. and evening hours.

Asheville facility. According to Nilsen, “The site here has a grassroots green team program that is run by associates on the floor, and projects like the LED lighting project are completely endorsed by, supported by, and championed by the green team.”
According to Scott Self, the lighting project in Asheville was a glowing success, resulting in big improvements to the site, great feedback, and reduced energy costs. “These results continue to instill our confidence in the project and in the rollout, and certainly, we are positioned to move forward with many more sites.” CA
