Applying Engineering Knowledge to Everyday Life

Often,our technical knowledge provides useful information that is greatly appreciated. Most of us have been asked questions about digital TV transition, cell phone coverage problems and cable or satellite TV trouble. We hear about about computer and Internet problems, too—even if we are RF/microwave engineers. Here is one example currently in the news: the savings achieved with compact fluorescent lamps (CFLs) and LED lighting instead of incandescent bulbs. There are a number of different light bulb sizes, and equivalent CFL or LED products, but for this exercise, let’s compare a 60 watt incandescent bulb, a 15 watt CFL and an 8 watt LED light.
