YYB said: The manufacturing process has been around for too long now for that answer to be valid. I never saw a technology take so dang long to take off and become cheaper via economies of scale. Like cheap and easy civilian trips into space? We've only been waiting on that for, what, sixty years?

There are literally billions of LEDs produced today, replacing traditional lighting in automotive, display, cell phone and camera flash applications, driving down cost, improving performance. So the technology has come a long way in a relatively short period of time, continues to grow.
Residential lighting adds many additional challenges: 1. LEDs are low voltage DC, converter required to run 110 or 220 V AC. Now, if new homes, businesses were wired for low voltage DC... 2. Color - the human eye is VERY sensitive to color, LEDs typically emit primary colors (red, green or blue), filtering is required to create light that is comparable to traditional lighting - not easy 3. Consumers are resistant to change, many are fighting regulatory efforts, unwilling to give up on incandescent bulbs for CFL, despite the shorter life, inefficiency
Plus, suppliers know that since LED bulb life is so long, they won't move much product after the mass conversion. The ridiculous prices should eventually be driven down by competition, but who knows how long that will take.
