Plug loads refer to energy used by equipment that is plugged into an outlet. In an office, key plug loads include computer and monitors, printers, and copiers. Plug loads can average approximately 30% of electricity use in office settings, much of which can be attributed to parasitic loads.
Pacific Northwest National Laboratory (PNNL) evaluated an LED replacement lamp that uses the same four-pin socket and electronic ballast as an incumbent CFL. Results showed energy savings between 40-50%, matching light levels and quality and payback under 3 years at the national average utility rate.
