The lighting levels in the Ahlstrom plant ranged from 30 foot-candles (fC) under the older 1,000W metal halide bulbs up to 85fC under the newest ones. The uneven, multi-colored lighting had become unacceptable to management. TEU was selected for the project after some in-house testing.
To provide the best solution, TEU's engineering team started with a photometric design that promised to deliver 55fC evenly throughout the facility. Since the maintenance crew at the plant had no experience with lighting designs or photometrics, TEU decided to conduct a pilot install. Upon completion of the pilot install, tests revealed that 57fC was achieved, exceeding the design by 2fC. 5000K LED highbay fixtures were installed in the entire facility, reducing the energy consumption by 71% and providing an even 57 foot-candle illumination.
