When LEDs come into mass production, to the extent of CFLs, that will
fix the cost effectiveness ... a good LED consumes 50% the power of a
CFL, or better ... this efficiency is not as advanced as it will be in
the future.

I'll buy that - I think LEDs will be ubiquitous in the future, and
will be able to serve almost every need.

I bought some LED spotlights for our back path. Run on three "D" cells, IR
activated by motion sensor. The first time I turned one on, it near blinded
me.. it throws a light path for well over 100'... Batteries are supposed to
last around 2 years.
