I bought some early LED spot lights for home.<p>These things cost $55 each and gave out a light that was a bit too dim, and very, very blue. My wife hated them and we took them out and put incandescents back to get the light we wanted.<p>We hated CFCs too - way too dim, and they take a long time to warm up (we tend to turn off the lights we're not using).<p>I'd love to see how good these newer LED bulbs can be in the real usage.
For comparison, this is about 10x the efficiency of an ordinary incandescent lamp.<p>EDIT: today's Fast Company story is better: <a href="http://news.ycombinator.com/item?id=2311641" rel="nofollow">http://news.ycombinator.com/item?id=2311641</a>
