I have found letters of commitment from both GE and Phillips stating "all of its self ballasted compact fluorescent lamps which are sold or made available for sale in the United States meet the mercury dosing limits contained in the Voluntary Commitment Requirements document (or NEMA standard) posted on the NEMA web site. Does that mean that all screw-based CFLs from GE and Phillips can be excluded from the purchasing plan and performance calculation?

If not, then how do you determine which ones are compliant on an individual basis?
