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.

There seems to be a surge in LED usage lately, mostly in cars and
traffic lights. I do like LEDs. They literally stay cool. But
expensive,for now.
