I did a short search and I found this:
ON December 16, 2011, the U.S. House passed the final 2012 budget legislation, which effectively delayed the implementation until October 2012.
Exemptions: There are 22 types of traditional incandescent lamps that are exempt. DOE will monitor sales of these exempted lamp types after the legislation is implemented. If it is determined that of any one of these exempted lamp types doubles in sales, EISA requires DOE to establish an energy conservation standard for the particular lamp type. This provision will prohibit any one of these exempted lamp types from taking market share from the general service lamps that are affected by the EISA efficiency standards.
