The movie industry, perhaps the last world dominating industry in California, should particularly appreciate this. As far as I know there are no non-incandescent lamps useful for film. For that matter even still flash's are incandescent - bye bye evening photography in Cali.
Yep! They are screwed....or will get an exemption from Nancy Pelosi. Fluoresent light spectrums are heavy on the yellow side. Guess it doesn't really matter since the vast majority of crap is now CGI.
Movie studios require a lot of light, and those studio lights use a lot of power. Theatrical lighting too is usually incandescent.
Perhaps the bill should first be set up to forbid any state legislator or government worker from purchasing or otherwise newly acquiring any incandescent bulbs after July 1, 2007. If they aren't willing to live without incandescent bulbs, why should anyone else?
