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).
Lead is used to make bearings and solder, and it is important in rubber production and oil refining. Lead production dates back at least 8,000 years. Lead was used in Egypt as early as 5,000 B.C. , and in the time of the Pharaohs it was used in pottery glazes and as solder. It was also cast into ornamental objects.
