I've heard that a lab applied some nanoparticles with a binder material
and that it emits light nearly equivalent to incandescent lighting.
They termed it "solid state lighting."
I was reading about it on the physorg.com web site as well and came
across a story about it on CNN.
They're estimating 3-5 years to ramp up production. It'll probably be
expensive to begin with (as were compact flourescents) then roll off as
production ramps up. It's a really fascinating application of nanotech,
IMHO.

At our campground (we use in the summer), we have LED outdoor pathway
lighting that is run from rechargeable batteries that are charged via
small solar panels on each outdoor light.
I can tell you this, the LED's do a very good job of lighting the
pathway, they are so efficient that the little "AA" batteries power them
all night (up to 12 hours), and what's' really remarkable is that they
do not draw any insects. It's kind's funny because my orange outdoor
bug light has all manner of bugs around it, but each of the white LED
lights have none. ;-)
Have a great weekend!

I'm not the slightest bit surprised that there are some in use right
now.
There was a time when only a small group of a certain type of people had
computers in their homes. Here's to hoping that the timeframe is closer
than my friend and her peers think. :-)
