Well, this low power consumption is still one of the main advantages of LEDs, though improvements in technology have made it possible to make them much brighter than before, and in a rainbow of colors. Instead of just being bright enough to be seen, as the earliest ones were, new LEDs are bright enough to be considered as an alternative to—and often an improvement…
