Peter has left a new comment on your post "California Incandescent Light Bulb Ban Takes Effec...":
Yes, somewhat ironically, ordinary bright cheap 100W light bulbs are
the first to go in most jurisdictions, not just California - given that low cost brightness
is such a problem with both CFLs and LEDs.
The unpublicised industrial politics behind the EU and US ban, with
documentation and copies of official communications:
Why supposed energy savings are not there anyway:
with US Dept of Energy references = Under 1% overall energy savings
from energy efficiency regulations on incandescent lights.
All lights have their advantages, and even if there were energy savings,
citizens pay for the electricity they use.
There is no energy or electricity shortage justifying a limitation on what
citizens can use,
and if there was a shortage of finite coal/oil/gas, the price rise
limits the use anyway - without legislation.
Emissions? Light bulbs don't give out CO2 gas -power plants might.
For any supposed energy supply/emissions problem - deal with the problem!
