Implementation Tactics

In addition to utilizing the appropriate lighting products, the implementation method of a lighting upgrade can have a serious impact on its success. To ensure favorable reaction and support from employees, they must be involved in the lighting upgrade. Educat ing employees and allowing them to participate in the decision process of an upgrade will reduce the resistance of change to a new system. Of critical importance is the maintenance department, because they will have an important role in the future upkeep of the system.

Once the decision has been made to upgrade the lighting in a particular area, and a trial installation has received approval, a complete retrofit should be completed as soon as possible. Due to economies of scale and minimal employee distraction, an all-at-once retrofit is usually optimal. In some cases, an over-night or over-the-week-end installation might be preferred. This method would avoid possible criticisms from side-by-side comparisons of the old and new systems. For example, a task lighting retrofit may appear darker than a uniformly illuminated space adjacent to it. The average worker who believes "more light is better" might protest the retrofit. However, if the upgrade is done over the weekend, the worker may not easily notice the changes.
