What is the Difference Between Led and Lead? The main difference between led and lead is tense. Led is the past tense of lead. She leads the way to prosperity. She led the way to prosperity. One of these examples is happening now (present tense) and the other has already happened (past tense). The problem, however, is that the past tense led is pronounced exactly like lead (a soft, toxic metal).
LED lighting differs from incandescent and fluorescent in several ways. When designed well, LED lighting is more efficient, versatile, and lasts longer. LEDs are âdirectionalâ light sources, which means they emit light in a specific direction, unlike incandescent and CFL, which emit light and heat in all directions. That means LEDs are able to use light and energy more efficiently in a multitude of applications. However, it also means that sophisticated engineering is needed to produce an LED light bulb that shines light in every direction.
