Get the most out of your commercial lighting system by following these steps: - Clean lamps and fixtures at least once per year to maximize light output. - Establish an ongoing maintenance program that emphasizes group relamping and proper disposal. - Consider automated lighting controls (where appropriate) to save energy and use lighting only when needed. - For your next lighting upgrade, design a lighting system that meets the specific needs of the building occupants and optimizes the available space. - Remember that environmental conditions can impact the performance and lifespan of lighting systems. Fluorescent lamps, for example, often don't perform as well in cold temperatures.
