Hologic Inc approached Northern Energy Services looking for solutions to their lighting needs. The main issue was the lack of light produced by the warehouse fixtures. During the no cost energy audit we discovered that due to the improper spacing and age of the lights, the desired light was not being produced.
We designed and implemented a turnkey solution using the latest high efficiency, high output fixtures. Once installed and properly spaced, the fixtures created a much brighter, more uniform spread of light. This combined with the installation of occupancy sensors drastically reduced the energy consumption of the warehouse.
