There is a large push in the united states currently to convert incandescent light bulbs more energy-efficient technologies, including compact fluorescent lights and light-emitting diodes. The lumen [lm] is the SI unit of luminous flux, a measure of the perceived power of light. To test the power usage, you run
an experiment and measure the following data. Create a proper plot of these data, with electrical consumption (EC) on the ordinate.
