You can still use the incandesant bulb after 2014, they just cannot be sold after 2014. So stock up a lifetime’s worth now, and you should be all set for the ban.
And actually, I think that there are some new bulbs that are "legal"...has something to do with lumens vs wattage consumed. Interestingly enough, the newer technology came out shortly before this asinine legislation. Purely coincidental, I'm positive. I'm also sure that lobbyists for Phillips, GE, etc were completely uninformed of the technology, or at least completely impartial.
I'll need to dig out the particulars on the bill. I do know that it does NOT mandate CFLs, it mandates a low-power-consumption bulb. CFL's are just the most common type.
Why am I imagining a “Blade Runner” future, where, instead of seedy characters on street corners selling illicit drugs, they open their overcoat to all types of Edison light bulbs? ;-)
