“LEDs, which last orders of magnitude longer than incandescent bulbs, typically slash the energy required for lighting by as much as 80 percent. They have been used in some display and signaling applications since the 1970s, but because they come with high price tags, they have yet to garner a significant portion of the general illumination market. So large installations by companies like these mark important progress for LEDs.”
“Increasing efficiency and decreasing costs are expected to make the technology more competitive during the next few years—and incandescent bulbs are being phased out by law. So LEDs, which have long been expected to disrupt the lighting market, may finally be poised to do so.”
