For legacy lighting sites (fluorescent, incandescent, sodium, etc.) transitioning to LED is one of the single most impactful measures to reduce energy consumption and utility cost. Changing to LED lighting can even reduce HVAC cost as building heat load is reduced. LED technology has been a game changer for lighting changeout costs and return on investment.
There are emerging, viable lighting technologies that will take the lighting industry into another generational leap forward. For example, POE (Power Over Ethernet) lighting can simplify your installations, reduce contractors on buildouts, and reduce overall costs if engineered correctly. Lighting controls can easily be implemented into the BAS (Building Automation System) that controls HVAC, security, access control, cameras and other similar systems that an facility manager uses on a daily basis.
