The Michigan House passed a bill that would allow a manufacturer to violate federal light bulb efficiency standards if they produce and sell those bulbs inside of Michigan.
Of course, this is just a publicity stunt as the passage of such legislation is unlikely to change the global economics of light bulb manufacturing.
While the bill is unlikely to have any productive outcome, the bill could discourage the innovative lighting companies here in Michigan that are trying to build their businesses. While Michigan does not and has not built low-efficiency incandescent bulbs, there are Michigan companies leading the way on LED bulbs.
