We ban because we can 

I noticed newer cases of T12 fluorescent lamps having a note that they're not for sale in certain states. I think WA and CO to name a couple.

I'll have to take a good look through my stuff & see if there's anything I think I'll need in the coming years & get it (probably by summer)

I know I'm fine for standard T8 & T12 .lol. even if I was to run my lights 24/7, I'd never live enough more years to burn them all up.
Its mostly the longer T5 NO & HO that I need to have a look through (... and especially anything aquarium/plant related!)
