Also note that these are efficiency standards. Incandescent is not
banned.
But since it bans lights that don't make the efficiency standard and
incandescents by their nature (and physics and...) can't make the
efficiency standard, they are banning incandescent lights by any
definition of the word used outside of DC.
Two Philips A19 halogens and four GE A19 halogens meet the efficiency
standard. Four other GE A19 halogens, "Reveal" ones, meet a lower
efficiency standard that applies to "modified spectrum". The Philips ones
achieve the efficiency spectrum by using "HIR" technology. The GE ones
apparently to me use premium gas mixtures and shorter filaments to reduce
heat conduction loss and also slightly increase filament temperature, along
with achieving barely the lumen standard at the highest wattage the
standard for a specific wattage range each lumen standard applies to.
I have seen the Philips ones at Home Depot, and the GE ones at Target.
Most R, BR and PAR incandescents with medium base and light output
310-2600 lumens already have to meet an energy efficiency standard that is
fairly easy for incandescent to meet. The 2012-2014 "ban" does not make
things any worse for these.
The 2012-2014 "ban" has many other exceptions:
* Design light output outside the range of 310-2600 lumens
* Design voltage outside the range of 110-130V
* Base other than E26/E27
* Globular at least 5 inches in diameter, tubular if over 10 inches long
or not exceeding 40 watts
* Flame shape and "S" (partial sphere on a cone) bulbs and many popular
globular bulb sizes if 40 watts or less
* "Specialty type" such as colored, bug, blacklight, infrared,
silver-bowl-tip, left hand thread, shatter-resistant, rough/vibration
service if 60 watts or less, appliance/"home oven" if 40 watts or less,
traffic signal, plant light, mine service, marine, sign, and a few others
