Abstract
Apparatus and method for comparison of electric power efficiency of lighting sources includes electric power supply to a first circuit and first light, and electric power supply to a second circuit and second light, and a first light meter and a second light meter to measure the light intensity of the first light and second light respectively and a clamp-on ammeter on the electric power line to the first light source and a clamp-on ammeter on the electric power line to the second light source and each clamp-on ammeter connected to a separate window in a computer to show the amperes drawn by each light source, and each light meter connected to a window in the computer to determine equal light from each lighting source.
