The difference between LED Lighting and Induction Lighting

A couple of decades ago, incandescent bulbs were the sole lighting choice. Now, various new lighting technologies compete for market share. Below, we contrast two kinds of new lighting technology: induction and LED light. Both induction and LED technology are superior to Edison’s original incandescent bulb, namely because incandescent bulbs operate by heating a filament. Therefore, most of the energy (95 percent) in an Edisonian bulb is lost to heat.

LED technology, in contrast, uses hyper-conductive materials and shifting atomic charges to create light. Every particle in an atom has either a negative or a positive charge. When an LED lamp is turned off, every particle has its match – all the negative ions are linked to positive ions. Engineers design LED lamps to turn on via atomic imbalance; they attach the negative side of a battery to negatively charged material and the positive side to positively charged materials. By forcing this atomic imbalance, designers cause LED light chips to glow with intense light as free electrons move toward positively charged atoms. (LED materials are unique in that they emit various colors of light as their electrons search for positive particles.)
