"In a move that could be called anything but conservative, Republican lawmakers are set to bring a bill to the House floor next week that will repeal state and municipal rights to set efficiency standards for light bulbs. The bill would unravel a piece of federal legislation that was strongly supported by light bulb manufacturers and has spurred innovation in the lighting industry.
The bill, sponsored by Texas Republican Joe Barton, would strip away any “federal, state or local requirement or standard regarding energy efficient lighting” that uses light bulbs containing mercury. In other words, all compact fluorescent bulbs.
Remember, in May, Barton, denied there was any “medical negative” from mercury emitted from coal power plants. Now he fancies himself a protector of the public from a vastly smaller source of potential mercury poisoning. The reality: There is an extremely small amount of mercury in CFL bulbs. Even after more than 8 hours of exposure, mercury levels are equal to eating a 6 oz can of tuna."
