Colorado recently became the seventh state to ban nearly all fluorescent lamps. The other six states are: California, Hawaii, Maine, Oregon, Rhode Island, and Vermont. The above chart shows the effective dates for each state’s phaseout of screw-based CFLs, as well as pin-based CFLs & linear fluorescent tubes.
All of the fluorescent lamp bans are based on mercury content rather than efficiency in order to avoid preemption by U.S. DOE appliance efficiency standards. More information from ACEEE is available here.
